The color blue is universally loved. No matter the hue, blue evokes feelings of class, peace, tranquility, and royalty.  Blue gems are no different; they have captivated humanity for years. From Egyptian pharaohs to modern royalty, blue gemstones have adorned the most relevant people in history. The deep blue of a sapphire or the ocean vibes of aquamarine speak to something deep within us.

All throughout history, blue gemstones held special meaning in religious artifacts and royal collections. Many civilizations believed blue stones connected them to the heavens. Royals chose blue gems to represent their right to rule.

 

We are going to, in this guide, explore the amazing spectrum of blue gemstones - from rare ones like Kashmir sapphire to accessible options like blue topaz. No matter what you are attracted to, every blue gem offers its qualities, appeal, and story. 

This guide is going to take you through:

• Which blue gems are hard and durable enough for daily wear?
• What are the different color and clarity grades for each blue gem?
• Any heat or enhancement treatments, and how important are they in selecting the right blue gem?
• Style pairings that can take a blue gem from a stone to a stunner.
• Smart investments and what to look for to verify authenticity.

Let’s dive into the world of blue gems, where meaning meets beauty and each tone tells a tale. We will start with precious gems, then semi-precious and other notable blue gemstones.

Precious Blue Gemstones

A. Blue Diamond

Blue diamonds are some of the rarest treasures on planet Earth. To put it into perspective, only 1 in 200,000 diamonds shows a natural blue color. These phenomenal gems form deep underground over millions of years. The stunning blue color is formed when boron atoms are trapped during the formation process. 

The most famous blue diamond in the world is the Hope Diamond. 

This historical 45-carat gem has fascinated people for centuries. Its mysterious history and deep blue tone make it priceless. It now lives in the Smithsonian Museum for everyone to admire.
Other blue diamonds have stunned the world with their amazing characteristics. The Blue Moon Diamond sold for over $48 million in 2015.

Another blue diamond famed for its features is the Oppenheimer Blue.

This 14-carat emerald-cut wonder sold at auction for a whopping $57 million in 2016!. These prices reflect the value of blue diamonds on the gemstone market.

Due to advancements in modern technology, scientists can now create blue diamonds in labs. The stones are identical to natural ones. In fact, the difference cannot be seen with the naked eye. Specialized equipment is required for that. Natural blue diamonds cost a lot more than lab-grown ones. 

In the gem world, blue diamonds are graded by color intensity just like other Fancy Colored Diamonds.

As you can see above, Faint Blue diamonds show a hint of color. Fancy Vivid and Fancy Vivid show deep, saturated tones. Stronger color intensity means higher prices and higher rarity.

Investment experts consider blue diamonds perfect long-term holdings. Over the past decades, blue diamond prices have increased steadily. Celebrity endorsements have also helped, with many adorning them for red carpets. This has increased its demand.

B. Kashmir Sapphire

Kashmir sapphires. You may be wondering if Kashmir sapphires are another type of blue sapphire. Well, yes and no. They are indeed blue sapphires; however, they truly deserve their special category. Their incredible beauty and status set them apart from any other sapphires in the world.

They come from a specific region in the Himalayan mountains. 

The original mines produced gems for only a few decades in the late 1800s. Today, genuine Kashmir sapphires are extremely rare. The unique velvety blue appearance is what sets Kashmir sapphires apart. Tiny silk inclusions create a soft, dreamy look. This unique beauty cannot be replicated in other locations.

The sad thing is, mining in Kashmir ended a long time ago due to harsh conditions. First off, it sits over 14,000 feet above sea level. New mining is almost impossible due to political tensions. Because of this, prices have risen to extraordinary levels.

Kashmir sapphires are hard to authenticate. Special equipment is required to identify characteristics and unique inclusions. Certificates from labs add a lot of value. Without proper documentation, you risk buying inferior or non-genuine stones.

Kashmir sapphires break auction records. Just months ago, a 35.09-carat Kashmir sapphire sold at Christie’s for a staggering $9.5 million! 

Another set the record for the largest Kashmir sapphire ever sold, weighing 55.17 carats and going for $1.5million.

These prices reflect their extreme beauty and rarity. Kashmir sapphires are considered by many collectors to be the ultimate prize. Investment potential remains excellent due to its limited supply. Very few Kashmir sapphires enter the market today.

C. Blue Sapphire (Non-Kashmir)

Yes, sapphires come in many colors: purple, pink, yellow, green but they are most popularly blue.  Blue sapphires from other areas offer beautiful alternatives to Kashmir specimens. Ceylon(Sri Lankan) sapphires show bright blue colors. Myanmar sapphires display intense, royal blue hues. Australian sapphires may be a little darker.

Most blue sapphires may have undergone heat treatment to improve their clarity and color. This process has been used over millenia. Heated sapphires usually cost less than untreated stones. Both types are great jewelry choices for different budgets.

Blue sapphires represent loyalty and wisdom in engagement rings. When the late Princess Diana of Wales selected her iconic engagement ring, she cemented its popularity worldwide.

Sapphires are very durable, ranking a 9 on the Mohs scale. Only diamonds and Moissanites rate higher. 

This durability means sapphire jewelry can last you generations. Chipping and scratching will rarely occur with proper care and maintenance.

Compared to blue diamonds, they provide incredible value. Large, high-quality sapphires will cost less than similar diamonds. Smart and discerning buyers appreciate the beauty-to-price ratio sapphires offer.

III. Semi-Precious Blue Gemstones

Semi-precious blue gemstones offer stunning beauty, excellent characteristics, and more affordable luxury. With their mesmerizing color to their rich history, they deserve their spotlight.

A. Tanzanite

Your journey into blue gems has brought you to one of the most amazing gem discoveries in modern history. Tanzanite did not exist until 1967. A tribesman found the blue crystals near Mount Kilimanjaro in Tanzania.

It is the only location of tanzanite on Earth. It is treasured for its exotic origin and rarity. Its pleochroism - the ability to show different colors from different angles. 

Sometimes, when tanzanites have brown undertones, heat treatment is applied to eliminate those and bring out the best in their blue hues. 

Almost all tanzanite receives this treatment. Don’t worry, heat treatment is standard practice since tanzanite was discovered. Without treatment, most tanzanite will have an unattractive brown color. Heat treatment transforms raw tanzanite from brown to brilliant blue. 

Promoted heavily by Tiffany’s, tanzanite cemented its place among top gems and, through marketing campaigns, became the birthstone for December. This pronouncement created global demand overnight.

Many scientists predict tanzanite mining will cease within the next couple of decades. Mining rates suggest supply will run out very soon. 

This limited future makes tanzanite increasingly valuable for collectors. Investment experts observe tanzanite prices for appreciation potential. Heavy, high-quality stones have increased in value steadily. Smart buyers focus on larger stones with great color uniformity and saturation.

B. Aquamarine

Aquamarine means “water of the sea” in Latin. This perfect description of its ocean-blue beauty. Aquamarine belongs to the beryl family, the same as emerald. Its blue color is caused by the iron content that ranges from pale sky to deep sea.

The finest aquamarines in the world come from Brazilian mines. The Santa Maria variety is the most prized for its deep blue color. These stones command top prices in the marketplace. Other sources include Nigeria, Pakistan, and Madagascar, each offering unique color features.

Aquamarines grow to jaw-dropping sizes in nature. Gem cutters can create spectacular large stones from these enormous crystals. Currently, at the Smithsonian Museum, sits a whopping 879-carat aquamarine called the Dom Pedro!  This size availability makes aquamarine perfect for statement jewelry pieces.

Like many precious and semi-precious stones, unwanted tones can be present in aquamarines. In that case, heat treatment is used to create a purer blue color that buyers prefer. This process is not only stable , but it is permanent and widely accepted in the gem world. The difference between treated and completely natural blue aquamarine cannot be told by the naked eye.

Aquamarines have excellent clarity, making them perfect for precision cutting. Skilled gem cutters love displaying their alluring color using brilliant step cuts and emerald cuts. With its transparency, light performance is optimal, rivaling that of more expensive gems.

Aquamarine offers you outstanding value across many quality levels. Even modest-grade stones show a stunning blue color. Higher grades display impeccable clarity and color saturation. This range makes it accessible to buyers with different budgets.

C. Blue Spinel

Blue spinel sometimes gets overlooked when we discuss blue gemstones, but this oversight represents a missed opportunity. Throughout history, many famous “sapphires” are spinels. In the British Crown, a famed red stone, originally thought to be a ruby, turned out to be a sapphire. 

Cobalt-colored blue spinels show some intense blue colors in the gemstone world. These specimens display a stunning electric blue that is comparable to some of the finest sapphires. The presence of cobalt creates the color. Natural cobalt blue spinels are quite rare and expensive.

Most gem-quality blue spinels come from Myanmar and Sri Lankan mines. The Mogok region of Myanmar yields specimens with excellent clarity. Sri Lankan spinels show lighter blue shades that have exceptional transparency. Each location produces different color features and qualities.

Synthetic blue spinel has been created for decades, creating market confusion. Lab-grown spinels are optically identical to natural stones. Only experienced gemologists with specialized equipment can tell the difference. This availability makes authentication very important.

The gemstone market recognizes spinel’s beauty and worth. Collectors look for fine blue spinels as more affordable alternatives to costly sapphires. Investment potential grows as more people discover its excellent properties. Its durability rating of 8 makes spinel perfect for any type of jewelry.

D. Natural Blue Topaz

Natural blue topaz is actually quite rare in its natural form.  Most blue topaz you will find in stores has received artificial treatment. This irradiation and heating process creates that alluring blue color that people love. There are three main varieties: Sky Blue, Swiss Blue, and London Blue. Each of these shows different intensity levels.

Sky Blue topaz displays the most delicate, lightest blue shade. Swiss Blue shows a moderate intensity with excellent brightness. London Blue offers the most saturated color available. Each variety appeals to design taste and style preferences.

The treatment process for blue topaz involves nuclear irradiation followed by a heat treatment. This combination permanently changes the color of the stone. All treated stones have to be stored safely until radiation levels decrease. Credible jewelers only sell stones that pass safety testing.

Topaz ranks 8 on the hardness scale, so its durability is not in question. This means blue topaz handles daily wear excellently. Scratches and chips don’t occur with normal use. The hardness makes topaz ideal for rings and bracelets.

Blue topaz is quite affordable due to mass production. Large quantities enter the market from Brazilian sources, primarily. You don’t need to pay premium gemstone prices to enjoy its beautiful blue color. This availability makes it popular for fashion jewelry.

Ethical buyers should always ask about treatment when purchasing blue topaz. Credible sellers are obligated to clearly state any enhancement process used. This transparency helps buyers to make informed decisions. 

IV. Unique Blue Gemstone Varieties 

A. Larimar

Our journey now takes us to the Caribbean for a unique discovery. Larimar exists nowhere else on Earth except the Dominican Republic. This unique, exclusive geographic limitation makes every piece of larimar irreplaceable.

Larimar formed millions of years ago through volcanoes in the Caribbean. Hot volcanic gases and mineral-rich water come together to create this unique blue stone.

The pectolite mineral composition gives it its distinctive appearance. Many similar minerals have been found elsewhere, but none match its incredible blue color.

The stone’s patterns remind people of ocean waves and white sand on the beach. Swirling white and blue colors flow together, creating a mesmerizing vortex of hues. Some pieces show sky blue shades while others have a deep ocean blue. 

Local miners work small-scale operations to extract larimar through a very careful process. The limited mining area covers a few square miles. Environmental concerns and issues with sustainability affect future mining plans. This restricted supply keeps its price stable and maintains its investment potential.

People believe larimar promotes relaxation and peace. It is often credited with healing properties by spiritual practitioners. You don’t need to believe all that to feel its peaceful effect due to its calming appearance.

B. Lolite (Water Sapphire)

This unique stone earned the nickname “water sapphire” due to its exceptional crystal clarity and distinctive blue color. However, iolite has nothing to do with sapphires at all. The cordierite mineral composition creates different properties. This confusion is common, as casual observers may perceive blue gemstones as being the same.

The most interesting aspect of iolite is its pleochroism. When you turn an iolite stone in different directions, the colors change dramatically. One angle shows a deep blue-violet, another shows a pale yellow, and a third displays a clear white. Every viewing angle is a new way to enjoy this stone.

Viking navigators used Iolite as a navigation tool during ocean journeys. Its pleochroic properties were an aid to locate the sun’s position even on cloudy days. It was called the “ Viking compass stone”. Whether this historical use is legend or fact, it appeals to the story of this amazing gem. Iolite is yet another affordable alternative to other stunning blue gemstones. 

Iolite’s color is categorized as “violetish-blue” by the GIA. Its optical properties of iolite appeal to collectors who love unique, underrated gemstones.

V. Selecting Your Perfect Blue Gemstone

Now, we are at the exciting part of this journey. Choosing the perfect stones for your needs. This isn’t just about picking the stone with the prettiest blue color.

Start by assessing your lifestyle and how you plan on wearing your jewelry - how often. Will you wear it daily or save it for occasions? Do you do a lot of physical work? Active lifestyles need more durable stones. Softer and more delicate gemstones are required for occasional wear.

Blue diamonds and sapphires are the strongest stones in our list. Their ratings of 10 and 9, respectively, mean they can resist scratching and chipping. These stones work perfectly for engagement rings and daily jewelry. Iolite and tanzanite need gentler handling but still suit regular wear.

Much softer stones like lapis lazuli and larimar require more careful handling. Save these gems for pendants and earrings, where they wouldn’t bump against surfaces easily. Consider your personality - are you careful with jewelry or naturally rough?

Color preference is also very important. Maybe you prefer pale, delicate blues over deep, saturated shades. There is a lightness and femininity with light stones, while dark blues evoke boldness and drama. 

Apart from preferring the tones, you have to factor in your existing wardrobe and jewelry collection. Pale aquamarine works with white metals and pastels beautifully. Deep sapphire blue works very well with bold colors and yellow gold. 

Your budget will determine which blue gemstones are going to be realistic options. Set a comfortable spending limit before you start shopping. Blue diamonds are a significant investment. Sapphire offers luxury at a slightly lower price point. Semi-precious stones provide beauty for a modest budget.

Think about the type of jewelry you want. Earrings can display softer stones safely. Necklaces allow for more dramatic gems.

Engagement rings need ultimate durability and brilliance. Some blue gems work better in certain jewelry styles than others. Faceted stones show fire beautifully. Cabochon cuts highlight star effects and transparency. 

Carved stones become artistic focal points. Size and scale are other important factors. If you are petite, you need to opt for smaller and delicate stones. Larger frames can rock substantial gems with confidence. Think about your hand size for rings. Your neck length when selecting pendants.

To prevent expensive mistakes, get professional consultation. They know which stones suit different styles and options within your range. Insist on certification for expensive gemstones.

Don’t rush this decision, especially for premium stones. Take time to research and educate yourself.

Don’t chase fleeting trends, but a trendy choice might lose appeal over time. Think about the story and meaning you want your blue gemstone to signify. Some people choose birthstones for personal significance. Others also select those that match achievements or milestones. The emotional connection means so much more than money.

VI. Blue Gemstone Care and Maintenance Guide

To make sure your blue gemstone remains beautiful for generations, it is important to take proper care of it. Different stones need different approaches. Hard gems like sapphires can handle more aggressive cleaning. Soft stones like larimar need very gentle treatment.

Most blue gems can be cleaned safely with a warm soap solution. Use a soft-bristled toothbrush for detailed cleaning around settings. Rinse and pat dry with a lint-free cloth. 

This method works for aquamarine, sapphires, and blue topaz. Avoid ultrasonic cleaners for softer gems and treated stones. The vibrations don’t help the color, and they can loosen settings. Steam cleaning works well for diamonds and sapphires only. When in doubt, use just gentle hand cleaning methods.

Store different gemstones away from each other to prevent scratching. Wrap each piece in a soft cloth or jewelry pouch. Store light-sensitive stones away from bright lights and windows. These can cause color fading and cracks in some cases.

Professional cleaning is very crucial to maintaining jewelry beauty. Jewelers have specialized equipment for thorough cleaning. They can check settings for loose stones, thereby preventing loss and keeping pieces secure.

Constantly check for signs that your stones need professional attention. Loose stones will shake in settings. Color changes might indicate a breakdown. Address problems quickly to avoid bigger ones.

VII. Market Analysis and Investment Guidance

Smart investors focus on specific blue gemstones with track records. Certified natural blue diamonds top the investment list. Their rarity ensures a price appreciation over decades. Only buy stones with vivid color grades for the best returns.

Untreated Kashmir sapphires with documentation offer investment potential. These legendary stones are becoming even rarer. Even small non-Kashmir sapphires command premium prices.

Fine tanzanite represents a great investment opportunity because of its single-source supply. High-quality stones over 5 carats show a strong appreciation potential. The limited mining area means a natural scarcity. Choose stones with great clarity and deep blue color.

Exceptional larimar with an intense blue color and minimal white veining appeals to investors. Its exclusive source limits supply forever. Market trends show growing appreciation for underrated blue stones. Blue spinel, for example, has gained recognition as a sapphire alternative.

Supply and demand factors drive blue gem varieties a lot. Prices and rarity are affected by mine closures. Discoveries can temporarily lower values as well. Supply chains are affected by political instability in countries. So all these factors are to be monitored.

Treatment acceptance works with different markets. Sapphires that are heat-treated sell at lower prices. Untreated stones command top-level valuations. Buyers are protected by disclosure requirements. Always ask for treatment documentation.

Lab identification becomes important for valuable blue gemstones. IGI, AIGS, and GIA provide trusted authentication services. Origin determination adds significant value to top stones. If you are going to invest, invest only in certified stones.

Color grading standards help to determine investment quality. Intense and vivid color grades perform best. Commercial-grade jewelry stones suit jewelry use but are not investments. Tone affect and saturation affect values more than just size.

Please note that market liquidity is different between blue gemstones. Blue diamonds and sapphires sell easily all over the world. Specialty stones like tanzanite are for specific markets. So, before you make an investment purchase, consider resale potential.
