What Are Lab Grown Diamonds?

Lab grown diamonds are real diamonds produced using advanced scientific methods that replicate the conditions in which natural diamonds form deep within the earth. The result is a diamond that is chemically, physically, and optically identical to a mined diamond.

HPHT Method

In the High Pressure High Temperature (HPHT) method, a diamond seed is placed into carbon and subjected to extreme heat and pressure, simulating natural diamond formation. This process crystallizes the carbon around the seed, forming a larger diamond.

CVD Method

The Chemical Vapor Deposition (CVD) method uses a sealed chamber filled with carbon-rich gasses and plasma technology. The carbon atoms bond to a diamond seed layer by layer, producing a stunning, eco-friendly diamond over time.

Lab Diamonds vs. Mined Diamonds

Are lab created diamonds real? Yes—lab grown diamonds are 100% real diamonds. They exhibit the same clarity, brilliance, durability, and grading standards as natural diamonds, without the environmental or ethical concerns of traditional mining.
