What are Lab Grown Diamonds?

Why Lab Grown Diamonds?

Leaf icon Mining Free
Lab created diamonds are a responsible choice given that no mining is required.
Lab diamond icon Beauty & Quality
Man made diamonds have the same physical, chemical, and optical properties as mined diamonds.
Shopping bag icon Value
Lab created diamonds offer excellent value, and are slightly more affordable than natural diamonds of comparable size and quality.

What Are Man Made Diamonds?

Man made diamonds, also known as engineered or cultured diamonds, are grown in highly controlled laboratory environments using advanced technological processes that duplicate the conditions under which diamonds naturally develop when they form in the mantle, beneath the Earth’s crust. These man made diamonds consist of actual carbon atoms arranged in the characteristic diamond crystal structure. Since they are made of the same material as natural diamonds, they exhibit the same optical and chemical properties.

Our lab grown diamonds are now readily available in a variety of colorless ranges. Cultured diamonds are also available in fancy colors that are considered very rare in nature, including popular hues of vivid fancy yellow. Fancy colored lab diamonds sell at comparatively reasonable prices compared to their natural colored diamond counterparts.

Lab Grown Diamonds vs. Diamond Simulants

It is important to note the major distinction between lab diamonds and diamond simulants. Diamond simulants, such as cubic zirconia and moissanite, look similar to diamonds but are not true carbon crystals. Simulants do not have the same chemical and physical properties as natural diamonds and therefore sell at much lower prices than man made diamonds. Simulants can be distinguished from natural or lab grown diamonds using only the naked eye.

Natural and lab grown diamonds have thermal conductivity properties that differentiate them from cubic zirconia with a handheld diamond tester. Some lab diamonds, along with some natural colored diamonds, may be mistakenly identified as moissanites when using certain diamond testers due to similarity in their electrical conductivity. However, gemologists can typically distinguish between diamond and moissanite due to their differing refractive properties, with moissanites being double refractive and diamonds being single refractive.
