type iia diamonds
Type iia diamonds are rare!
Less than 2% of all mined diamonds
can be classfied as Type IIa.

A diamond’s crystal structure is formed from a single element: carbon. Typically a diamond is 99.95% pure carbon and 0.05% trace elements, or impurities, that aren’t part of its essential chemistry.

Both Lab-Created and mined diamonds are scientifically classified by “type” The “type” is determined by the level and variety of the chemical impurities present in the diamond crystal.

Type IIa diamonds lack these chemical impuites and they also tend to have fewer inclusions; making them the purest form of diamond available.

Lab Grown Diamonds Are a Clear Choice


Lab-Created diamonds are identical to mined diamonds; sharing the same physical, chemical and optical properties. Both are faceted and polished in the same manner by skilled diamond cutters. The only difference is origin.


Lab-Created diamonds are a commitment to the sustainability of natural systems and our environment, allowing future generations to have the natural resources they need.


The guaranteed origin of a Lab-Created diamond ensures that you have a truly conflict-free diamond.
Eco-conscious Created in a facility with advanced technology, our Lab-Created diamonds have far less direct impact on the environment than mined diamonds.


Created diamonds are certified by the same leading independent gemological labs, using the same criteria, and the same grading standards as mined diamonds.
