What Are Marquise Cut Diamond Engagement Rings?

History and Origin of the Marquise Cut Diamonds

Marquise cut diamonds have a rich history. It dates back to the 18th century. 

King Louis XV saw a lady named Jean Antoinette Poisson in a masked ball attire in Versailles. 

Madame Poisson smitten Louis XV with her beauty and attire. So, he made her his chief mistress in the French Royal Court. After this, he placed her in his court as Marquise de Pompadour. 

King Louis recognized her lips as the most perfect lips in the world. So, the king commissioned a royal jeweler and asked him to create a jeweler design that mimics the lips of her mistress. 

Then, the diamond cut comes and is named after Marquise de Pompadour.

• Aesthetic Appeal: The cut's distinctive silhouette and brilliant facets make it a statement piece for engagement rings.

Understanding the 4Cs for Marquise Cut Diamonds

The 4Cs are fundamental for evaluating the quality and value of diamonds. They are cut, carat weight, clarity, and color. So, you will find no exception for Marquise cut diamonds, too. 

Each aspect is crucial in determining the diamond's overall appearance and appeal.

1. Diamond Cut Grade

• Elongated Shape

The elongated shape is a hallmark of the marquise cut. The shape emphasizes its uniqueness. 

Also, diamond fluorescence plays a role in the appearance of marquise diamonds. Fluorescence means the tendency to emit a soft-colored glow when exposed to UV lights. 

Diamonds with strong fluorescence may appear milky in daylight. These types of marquise-cut diamonds are considered good to poor.

Diamonds with no fluorescence are considered excellent.  So, evaluating this factor before purchasing is essential.

• Diamond Length-to-Width Ratio

The marquise-cut diamond length-to-width ratio determines the overall balance and elegance of the diamond’s shape. It is the calculation of the length of the diamond compared to the width. 

• Recommended Ratios: 

For a balanced look, a ratio between 1.70:1 and 2.10:1 is ideal for marquise-cut diamonds. A much longer size can make it difficult for the cutters to facet the face-up. This will reduce the appeal of the appearance of brightness. 

On the other hand, a very short length can make the diamond stubby. 

However, the length-to-width ratio could always be your personal preference. It should align with your personal style and fashion sense. 

However, a ratio of 1.70 can be durable with its thickness compared to a 2.15 ratio. The 2.15 will look much more elongated and will have slightly less durability. 

• Diamond Symmetry and Polish

Symmetry and polish significantly influence how light interacts with the diamond, affecting its brilliance.

To ensure a balanced symmetry, the endpoints of the diamond must be aligned with each other. Even a little imbalance in symmetrical cutting can create an off-order look. 

Look for uneven facets or misaligned points, which can detract from the stone’s beauty.

Also, poor polishing can create a dull finish of the diamond. So, look for the left and right sides of the diamond that create a near-mirror finish. 

Make sure the diamond has achieved a smooth and glass-like surface. 

• Table Percentage and Depth Percentage

The table has the largest flat surface on top of the diamond. The “Excellent” range for the table percentage is considered between 53% and 63%.

However, here is an overview of another evaluation category of the table percentage. 

The depth of the diamond is the distance between the table and the culet. The depth percentage ranging from 58% to 62% is considered “Excellent.” This ensures optimal light performance.

However, the following ranges fall into different categories. 

• Girdle Thickness and Culet Size
• Girdle Thickness: A very thin to slightly thick girdle thickness is preferred to balance durability and aesthetics. It is considered excellent for marquise-cut diamonds. But extra thin or extra thick is considered poor cutting grade. 
• Culet Size: Ideally, the culet should be none to ensure maximum brilliance. But a very small culet is considered very good, small is considered good, and medium is fair. If the culet is more than medium, it is considered poor. 
  

2. Diamond Carat Weight

The diamond carat weight is one of the most recognizable measures of a diamond's size and value. In general, the bigger the carat weight, the higher the price of the diamond. 

One of the unique aspects of marquise-cut diamonds is their elongated design. The cut design creates the illusion of being larger than other cuts of the same weight. 

Let’s check the significance of different carat weights:

• Small Carat Weights (0.30-0.75 ct): 

These diamonds are budget-friendly. Yet they appear substantial due to the marquise shape.  For example, a 0.30-carat Marquise cut diamond with VVS1 clarity and F-grade color can be priced at around $1,200. 

This type of smaller carat size is ideal for minimalist designs or those with smaller hands.

• Medium Carat Weights (1.00-1.50 ct)

The medium sizes are among the most popular choices for marquise-cut engagement rings. They offer a perfect balance of size, brilliance, and affordability.

A 1.00-carat marquise-cut diamond costs a minimum of around $5,000. The price can increase based on the clarity and color grades. 

• Larger Carat Weights (2.00 ct and above): 

Larger marquise diamonds make a bold statement. They are also often selected for their impressive visual impact. But they come with a higher price tag and require careful scrutiny of the 4Cs to ensure quality.

The marquise cut’s ability to escalate perceived size makes it a versatile option across different carat weights. However, larger carat weights may also amplify any imperfections. That is why it is important to consider the other Cs—clarity and color.

3. Diamond Clarity Grades

The diamond clarity refers to the presence of inclusions (internal flaws) or blemishes (external flaws) in a diamond. Due to the marquise cut’s elongated shape and pointed diamond tips, clarity is especially important. 

Because inclusions near the edges can be more noticeable. And more inclusion reduces the price of the diamonds. Conversely, the fewer the inclusions and blemishes, the higher the value of the diamonds. 

According to GIA’s clarity definitions, here’s a breakdown of clarity grades:

• FL (Flawless)

Completely free of inclusions and blemishes under 10x magnification. These diamonds are exceedingly rare and come with a premium price.

• IF (Internally Flawless)

No internal inclusions. But minor surface blemishes may exist. They are also rare and highly valuable.

• VVS1 and VVS2 (Very, Very Slightly Included)

It contains inclusions that are nearly impossible to detect under 10x magnification. These grades provide a balance of near-perfection and cost.

• VS1 and VS2 (Very Slightly Included)

They contain minor inclusions that are typically invisible to the naked eye. Diamonds with VS1 and VS2 have excellent value for most buyers.

• SI1 and SI2 (Slightly Included)

Contain inclusions that may be visible under close inspection or magnification. Affordable but require careful selection to ensure inclusions don’t detract from beauty.

Here is a table for marquise cut diamonds with clarity grade evaluation for particular carat weights. 

For marquise diamonds, we recommend you prioritize a clarity grade of VS2 or higher. 

4. Diamond Color Scale

Color significantly impacts the appearance of marquise diamonds. This is because their shape tends to reveal more color than round or princess cuts. 

The GIA diamond color scale ranges from D (colorless) to Z (light yellow or brown):

• D-F (Colorless): These diamonds are the most prized and appear icy white. They are ideal for white gold or platinum settings.
• G-J (Near-Colorless): Slight warmth is present. But they are often undetectable to the untrained eye. These diamonds offer excellent value.
• K-M (Faint Color): Noticeable color becomes apparent. But especially in larger stones. These can still be attractive in yellow or rose gold settings.
• N-R (Very Light): This color range often highlights any tint of color, making the yellow or brown tones more apparent. Diamonds in the N-R range are significantly less expensive than those in higher color grades. This makes them an economical choice for larger carat weights.
• S-Z (Light Color): These diamonds are less popular for engagement rings but may suit vintage-inspired designs.

Here’s a quick overview of the color scales of the marquise cut diamonds to evaluate their grade. 

When selecting a marquise diamond, aim for a color grade of G or higher to ensure a bright and vibrant appearance.

The Bowtie Effect in Diamonds

The bowtie effect in diamonds is a dark shadow that can appear across the center of the diamond due to light obstruction. When the light can’t be evenly distributed through the diamond, a black shade like a men’s bowtie is created. 

However, a slightly visible bowtie effect is common in Marquise-cut diamonds. Also, it only can be visible when you see the stone from a 90-degree angle. 

But an overly pronounced effect can detract from the diamond’s beauty. Examine the diamond under various lighting conditions to assess the bowtie effect. Ensure it complements rather than diminishes the overall appearance.

Choose a marquise-cut engagement diamond with slight bowtie effects. 

Certification and Authority

Diamond certification is essential to verify the quality and authenticity of a diamond. You should ask for the seller’s grading certificate for the diamond when purchasing one. 

Trusted grading authorities ensure that diamonds are evaluated consistently and transparently. 

Let’s explore the key certifications and their importance:

GIA (Gemological Institute of America)

The GIA is widely considered the most reliable grading authority. Their certification includes detailed assessments of the 4Cs, fluorescence, and other attributes. 

A GIA-certified diamond guarantees accuracy and peace of mind. You can check the diamond with the report number provided by the seller if they claim that GIA grades their diamond. 

IGI (International Gemological Institute)

The IGI is another respected certifying body, particularly for retail diamonds. While their grading standards may differ slightly from GIA, they are still reliable and commonly used.

Also, the IGI report is faster than the GIA and more affordable as well. You can check the IGI report with the report number, which is the same as the GIA. 

Key Details to Review in Certification

When reviewing a diamond’s certification, pay attention to the following aspects. 

• Clarity and color grades
• Cut specifications, including symmetry and polish
• Length-to-width ratio for marquise diamonds
• Presence of fluorescence

Purchasing a certified diamond ensures transparency. This enables you to make informed decisions with confidence. As a result, you can be assured that you are going to get the best value for money. 

Preferred Diamond Setting Styles for Marquise Cut Diamond Engagement Rings

The setting plays a vital role in enhancing the beauty and protecting the delicate tips of marquise diamonds. You can choose the popular options, such as:

• Prong Settings: It secures the diamond while highlighting its unique shape.
• Halo Settings: This adds brilliance by surrounding the diamond with smaller stones.
• Bezel Settings: Provide maximum protection by encasing the diamond in metal.
• Solitaire Settings: Focus on the elegance of the marquise diamond without distractions.
• Three-Stone Settings: Pair the marquise cut with complementary side stones for added flair.
• East-West Settings: Position the diamond horizontally for a modern twist.
• Pave Settings: Add extra sparkle with small diamonds along the band.
  
  

Cost Consideration for Marquise-Cut Diamonds

The cost of a marquise-cut diamond engagement ring depends on different factors. You should consider the following factors for the best value for money if you have a concern about the budget. 

• Carat Weight: Larger stones are exponentially pricier. A 1-carat marquise diamond ranges from USD 4,000 to USD 5,100, while 2 carats can exceed USD 9,500.
• Clarity: Higher clarity grades (FL, VVS1, VS1) cost more. But VS2 offers great value with minimal inclusions.
• Color: D-F (colorless) diamonds are premium-priced. At the same time, G-J (near-colorless) options balance quality and affordability.
• Cut: Ideal proportions with minimal bowtie effect set higher prices.
• Setting: Halo or pave settings add cost, while solitaires are more budget-friendly.

Focus your budget on the diamond’s quality and a protective setting for durability.
