OVERVIEW
Lab-grown diamonds are artificial diamonds generated in highly controlled laboratory settings by scientists. They possess the same chemical composition, carbon atom structure, optical qualities, and physical attributes as natural diamonds, making them equally stunning and durable. The main difference between natural and lab-grown diamonds lies in their formation process.
HOW ARE LAB DIAMONDS FORMED?
Lab-grown diamonds are created using two main procedures: High-pressure high-temperature (HPHT) and chemical vapor deposition (CVD).
In the HPHT process, scientists expose a tiny diamond crystal to pure carbon within a containment chamber, subjecting it to extreme temperatures and pressures. The exposure causes the carbon to melt, forming a lab-grown diamond around the diamond seed.
For the CVD process, a diamond seed is placed in a chamber, heated to extreme temperatures, and filled with a carbon-rich gas, which is ionized using microwaves or lasers. This results in pure carbon separating from the gas and forming a lab-grown diamond layer by layer around the diamond seed.
HARDNESS AND STRENGTH OF LAB DIAMONDS
Lab-created diamonds are sufficiently strong to be used in engagement rings, boasting a mineral hardness rating of 10 on the Mohs scale, just like mined diamonds. Most jewelers recommend a Mohs scale rating of 9 or higher for daily rings, and lab-grown diamonds excel in this regard with a perfect score of 10.
CLARITY OF LAB-GROWN DIAMONDS
Inclusions are imperfections similar to birthmarks found in both lab-created and mined gemstones, formed during the growth process of the gem or diamond. Inclusions may be visible or invisible to the naked eye, impacting the overall appearance and sparkle of the diamond.
Typical inclusions include needle-like, cloud-like, crystal-like, feather-like, and pinpoint-like inclusions. The type and number of visible inclusions determine the clarity grade of a lab-grown diamond.
CLARITY GRADES FOR LAB DIAMONDS
The International Gemological Institute (IGI) is a highly regarded authority in the diamond industry, with independent laboratories across the globe and reputable gemology academies. The IGI clarity scale assesses the internal and external imperfections in diamonds. It includes grades like IF (Internally Flawless), VVS1 (Very, Very Slightly Included 1), VVS2 (Very, Very Slightly Included 2), VS1 (Very Slightly Included 1), VS2 (Very Slightly Included 2), SI1 (Slightly Included 1), SI2 (Slightly Included 2), I1 (Included 1), I2 (Included 2), and I3 (Included 3). These grades provide valuable information about the clarity of a diamond, ranging from flawless to various degrees of inclusions that may or may not be visible to the naked eye or under magnification.
BENEFITS OF PURCHASING LAB-GROWN DIAMONDS
Purchasing lab-grown diamonds comes with several advantages:
- Cost-Effective: Lab-grown diamonds are more affordable than naturally formed diamonds, enabling customers to purchase stunning diamonds without breaking the bank.
- Genuine Diamonds: Lab-created diamonds are authentic and hold the same properties as naturally formed diamonds.
