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!
Carat
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, and larger diamonds tend to be more expensive. When it comes to smaller diamonds, an Ada Concierge may use the term “points” to discuss diamond weights with you. One point is one-hundredth of a carat (0.01). A “33 point diamond” would be one-third of a carat (0.33 carats).
Clarity
Clarity is a measurement of how many blemishes or inclusions are present in the diamond, which can be either defects in the diamond crystal or microscopic foreign particles within the diamond. The lower the clarity of a diamond, the more imperfections in the diamond. Clarity is graded on a range from Internally Flawless to Included. Ada only sells diamonds that are Very Slightly Included or better.
Color
A perfect diamond, with no impurities and no defects, is completely colorless. Impurities such as nitrogen cause undesirable yellow or brown tones in the diamond. Color is graded on a range of letters from D to Z — Ada Diamonds only sells stones are that are independently graded as colorless (D, E, F) or the best of near-colorless (G). All of Ada’s fashion pieces proudly feature only DEF.
Cut
The cut of the diamond is a measure of the quality of the shape, geometry, and finish of diamond gemstone. Only round brilliant diamonds receive formal cut grades on a scale from Ideal (the best) to Poor. Ada in uncompromising on cut quality to ensure all of our diamonds have optimal brightness, fire, scintillation, and maximum light performance. All of our rounds receive the highest cut grade offered by the grading lab (Ideal for IGI and GCAL, Excellent for GIA).
Why Choose a Lab Diamond?
The two main reasons our clients choose a lab diamond are origin and value. Rest assured that your diamond did not result in the funding of conflict in a war-torn country, nor did it require leaving a mile-wide hole in the ground. Read on for 6 reasons to buy a lab grown diamond!
Good vs Bad Lab Diamonds
Just like with mined diamonds, lab diamonds can vary significant in quality. You should always insist a lab diamond expert inspects your stone prior to purchase.
Lab Diamond Pricing
Lab diamonds are priced based on their 4Cs quality characteristics, just like mined diamonds. Lab diamonds are typically ~80% less expensive than mined diamonds of equivalent quality.
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.
Independent Certification
Ada's lab diamonds of larger than 0.5 carats are all graded and certified by independent gemological laboratories. These laboratories are not affiliated with Ada Diamonds and grade our diamonds on the same criteria that they grade earth-extracted diamonds. We primarily work with three laboratories: GIA, IGI, & GCAL

DIFFERENTIATION
Between Earth-Extracted Diamonds & Laboratory-Grown Diamonds
Ada agrees with the prestigious World Federation of Diamond Bourses that lab created diamonds must be clearly disclosed, documented, and differentiated. As such, we require every customer of Ada Diamonds to acknowledge the following during the purchasing process:
I acknowledge that I am purchasing laboratory-grown diamonds that are proudly created by scientists above the Earth, not extracted or mined out of the Earth.
