Pure Grown Diamonds

A New Choice In Diamonds

Certified & Sustainable

Pure Grown Diamonds are the preferred diamond supplier for Blumlux.

Certified, conflict-free, environmentally-friendly & sustainable. Pure Grown Diamonds are identical to mined diamonds – sharing the same physical, chemical and optical properties as their natural counterparts.

A Fair Market

It’s no secret technological advances in processes usually result in better prices for consumers.

Mined diamonds not only have high overhead costs, but the market is also determined by the limited supply of diamonds and the few diamond houses who control it.

Due to the advancement of lab grown diamonds, Pure Grown diamonds offer consumers the same qualities and features of mined diamonds, but, at more affordable pricing structures.

Pure Grown Diamonds

Lab-grown diamonds are produced using advanced technology that replicates the conditions under which diamond crystals (or rough diamonds) are formed. The rough diamonds are then cut and polished using the same tools and techniques used to cut earth-mined diamonds.


Lab-grown diamonds are identical to mined diamonds; sharing the same physical, chemical and optical properties. The only difference is the origin.


Grown in a facility with advanced technology, Pure Grown diamonds have far less direct impact on the environment than mined diamonds.


Pure Grown diamonds are committed to the sustainability of natural systems & the environment.

Guaranteed Origin

The guaranteed origin of a lab-grown diamond ensures that you have a truly conflict-free diamond.


Pure Grown diamonds are graded to the same standards by the same leading independent gemological labs as mined diamonds. Finally, Nick Blum personally inspects every diamond to ensure it meets Blumlux standards.


The girdle of each Pure Grown diamond is laser-inscribed with the unique, corresponding grading number to properly identify your diamond & its origin.

Certified as Type IIa Diamonds

A diamond is the only gem overwhelmingly made of a single element. It is typically 99.95% carbon. The other 0.05 percent can include one or more trace elements, sometimes called impurities, which are atoms that aren’t part of the diamond’s essential chemistry.

Diamond type is a method of scientifically classifying diamonds, both grown and mined, by the level and type of their chemical impurities.

Extremely rare in nature, Type IIa diamonds account for less than 2% of all the world’s mined diamonds.

Type IIa diamonds are almost or entirely devoid of impurities, and are considered to be the purest form of diamond known to man. They also tend to have few inclusions. Diamonds with the fewest inclusions allow the light to pass through the stone making them more beautiful and valuable.

Type IIa diamonds have superior brilliance with more scintillation or sparkle compared to other diamonds due to their purity.

All white and pink diamonds from Pure Grown are certified as Type IIa.

Growing Sustainability

“Mined diamonds represent more than 7 times the level of impact as compared to grown diamonds.”
