Learn About Lab-Created Diamonds

Lab-created diamonds (aka man-made diamonds, pure grown diamonds or cultured diamonds) are grown in highly-controlled laboratory conditions that simulate the earth’s natural growing environment, producing real diamonds that are optically, physically and chemically identical to earth-mined diamonds.

Our man-made diamonds are grown using one of two different techniques. Each process produces pure carbon diamonds when complete, however they are often used for different application. High Pressure High Temperature (HPHT) is our primary growing process, while Chemical Vapor Deposition (CVD) is commonly used to produce diamonds for industrial purposes. Learn more about the growing process.

Unrivaled Quality

Our lab-created diamonds are of superior quality. As type IIa, they are the purest form of diamond available, meaning they are harder and have more brilliance than a traditional type Ia diamond. Only 2% of earth-mined diamonds will ever get to the same level of perfection as every grown diamond.

All MiaDonna lab-created diamonds are graded and certified by the same leading independent gemological labs that are used to grade earth-mined diamonds.

Unbeatable Value

Our man-made diamonds are up to 40% less than their natural diamond equivalents. But buyers should beware: genuine grown diamonds that carry the characteristics and qualities of a mined diamond will never be sold for only a few hundred dollars per carat. If the deal seems to good to be true, it probably is. Only Diamond Simulants can be priced for a few hundred dollars per carat.

Guaranteed Conflict-Free

Every lab-created diamond from MiaDonna is guaranteed conflict-free, sourced from first world countries where they are treated and cut in a controlled modern-day lab environment.

Unlike earth-mined diamonds, our grown diamonds are created without negatively harming native communities, society or the earth

Furthermore, proceeds from every purchase at MiaDonna help our foundation, The Greener Diamond, build agricultural farms in Sierra Leone and Liberia, where child soldiers are supported to grow food instead of mining for diamonds.

Environmentally Friendly

Pure grown diamonds are an eco-friendly product. By choosing a man-made diamond versus an earth-mined diamond you're reducing the harmful impact mining has on the environment and native communities.

FACT: The amount of land disturbed in the creation of lab-created diamonds = 0.00000071 hectares/carat. The use of water is also minimized with approximately 70 litres used in the creation of a 1 carat grown diamond.
