Lab Grown Diamonds
Lab-grown diamonds, also known as synthetic or cultured diamonds, are real diamonds that share the same physical, optical, and chemical properties as mined diamonds. The primary difference between the two lies in their origin. While mined diamonds are formed naturally over millions of years under extreme pressure and heat deep within the Earth’s crust, lab-grown diamonds are created in controlled environments within weeks using advanced technological processes.
How are lab grown diamonds made?
The production of lab-grown diamonds involves either High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD) methods. HPHT replicates the natural conditions under which diamonds are formed, using high pressure and high temperature to transform carbon into a diamond structure. CVD, on the other hand, involves breaking down carbon-rich gasses to deposit carbon atoms onto a substrate, gradually building up the diamond layer by layer.
| Mined Diamond | Lab Grown Diamond | |
|---|---|---|
| Formation | Deep in the earth's crust | In a controlled lab setting |
| Composition | Carbon | Carbon |
| Time Period | Created over millions of years | Created in 4 weeks |
| Environmental Impact | Deforestation, soil disturbance, air emissions, ground water contamination | The carbon footprint is a very small percentage compared to mined diamonds |
| Durability on the MOH scale of hardness | 10 | 10 |
| Refractive Index | 2.42 | 2.42 |
| Price | Expensive | About 50% cheaper |
Grading and Certification
Lab-grown diamonds are graded and certified using the same process as mined diamonds. Internationally recognized grading gem labs grade diamonds on the basis of cut, color, clarity and carat. This determines their value, look and size. Some popular diamond certification labs are Gemological Institute of America (GIA) and International Gemological Institute (IGI). With every Diamond Chemistry piece you receive an IGI certification for the authenticity of your purchase.

Ethical and Affordable Choice
Lab-grown diamonds deliver exceptional value, offering the same dazzling brilliance as mined diamonds at a more accessible price. By opting for lab-grown diamonds, consumers support sustainable practices that significantly reduce the environmental and ethical concerns associated with traditional diamond mining. This empowers you to get more diamonds for your money, securing a dream piece without compromise.
