The Smarter Diamond

The process is simple but the equipment is sophisticated. Diamonds are made from a combination of heat, pressure, carbon, and time. We have essentially created the same elements in a controlled, eco-friendly laboratory.

Graded Quality & Integrity

All diamonds are graded by gemologists so you can trust the quality and integrity.

Eco-Friendly & Affordable

EX3 diamonds are more affordable and better for the environment since they are lab-created.

100% Conflict-Free Guaranteed

Because lab-diamond jewelry does not depend on earth-mining, our diamonds are 100% conflict-free.

Our Vision

Our Vision

Our motivation to produce EX3 diamonds was fueled by the quest to create the most brilliant, perfectly cut, man-made diamonds. Additionally, there has been an increase of “blood diamonds” in the market. By creating EX3 lab-made diamonds, we provided an eco-friendly solution to diamond mining. EX3 creates lab-diamond jewelry to preserve the earth and environment. This allows you to pass down these perfectly cut diamonds to future generations. Our sparkling, perfectly cut, high-quality, environmentally-friendly, conflict-free approach to selling diamonds will, hopefully, become widespread and consist of 50% of the world’s diamonds within five years.

Are These Real Diamonds?

EX3 Created Diamonds are real diamonds. They have the exact optical appearance, chemical composition, and physical properties as natural diamonds. The only difference is the origin and price. The technical term for EX3 Created Diamonds is chemical vapor deposition (CVD). GIA, the foremost trusted gemological laboratory, has begun certifying these diamonds to mediate their authenticity and value. EX3 man-made diamonds are NOT imitation diamonds. Do not confuse this product with CZ or moissanite. The process of making these diamonds is different but the end result is exactly the same. Carbon is compressed, vaporized, and laser cut. The lab-made diamonds are then cut and faceted using the same equipment used for earth-mined diamonds. The elements are exactly the same, the only difference is the origin.
