Why Ace Diamond?


Lab created diamonds are a responsible choice given that no mining is required.


Lab created diamonds have the same physical, chemical, and optical properties as mined diamonds.


Lab created diamonds offer excellent value, and are slightly more affordable than natural diamonds of comparable size and quality.


Ace 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. ACE 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.

How Are Ace
Diamonds Made?

Our lab created diamonds are grown from the tiny carbon diamond seeds of pre-existing diamonds. Advanced technology – either extreme pressure and heat or a special deposition process known as CVD – mimics the method of natural diamond formation.

Some lab diamonds grown through deposition may also undergo pressure and heat treatment after they are grown. Lab grown fancy colored diamonds are formed when small amounts of specific trace elements are present during the growth phase of the created diamond, just like in nature. In both white and fancy colored lab diamonds, the exact composition of trace elements may differ from their natural diamond counterparts. A lab diamond can only be distinguished from natural diamonds using specialized equipment that can detect the minor differences in trace elements and crystal growth.


Ace diamonds display the same physical, chemical, and optical characteristics as natural diamonds, and exhibit the same fire, scintillation, and sparkle. Using a jewelry loupe, man made diamonds are nearly impossible to differentiate from natural diamonds. Ace diamonds may exhibit different trace elements than natural diamonds that do not affect the appearance of the diamond. Ace diamonds can be distinguished from natural diamonds only with tests
using specialized equipment. Lab created diamonds available for purchase should always come with a gem certification identifying them as laboratory grown.
