Man Inspecting Lab Grown Diamond with Magnifying Lens

The Four Cs of Lab Created Diamonds:

Cut, Color, Clarity, & Carat Weight

Lab diamonds receive grading reports from independent gemological organizations on the 4Cs: Cut, Color, Clarity, and Carat Weight. Just like in mined diamonds, lab diamonds will exhibit variations across the 4Cs and range from poor to superlative quality. Not all lab diamonds are perfect, colorless, and flawless!

Cut

Cut

The carat weight of a diamond is a measurement of its weight. One carat is exactly one-fifth of a gram (0.20 g). When a diamond is properly cut, the carat weight defines the size of the diamond. When it comes to smaller diamonds, an Ada concierge may use the term “points” to discuss diamond weights...

Available Lab Diamond Shapes

Available Lab Diamond Shapes

Ada Diamonds offers ten shapes for center stones: round, oval, pear, cushion, princess, radiant, emerald, and asscher in addition to accent diamonds of baguette, trapezoid, half moon, trillion, and triangular brilliant.



No two diamonds are exactly the same, which is what makes the process of finding the best diamond both an art and a science. Each stone, mined or lab grown, has unique properties that determine the quality of its sparkle, fire, and life.

Ada Diamonds prides itself on sourcing the highest quality lab diamonds in the world and we avoid the mediocre diamonds that are sadly sold to many consumers. We don’t expect you to be a diamond expert, and we take seriously the responsibility of providing you with the best option possible. We refuse to sell unexceptional man-made diamonds.
