Introducing the 4 'C's

Cut

The cut of the diamond is a measure of the quality of the shape, geometry, and finish of a diamond gemstone and are graded on a scale from Ideal (the best) to Poor. Ada's gem-cutting partners ensure that our diamonds have optimal brightness, fire, scintillation, and maximum light performance. 

Color

The color of a diamond is graded on a range of letters from D to Z. Ada only sells stones are that are independently graded as D, E, F, G, or H and refuses to sell any diamonds that are I or worse color. Ada is also happy to work with fancy-colored lab grown diamonds in blue, pink, yellow, gray, and black. 

Clarity

Clarity is a measurement of how many blemishes or inclusions are present in the diamond. Clarity is graded on a range from Flawless to Imperfect; the lower the clarity of a diamond, the more imperfections in the diamond. Ada Diamonds only sells diamonds that are SI1 (no includes visible to the naked eye) or better. 

Carat Weight

The carat weight of a diamond is a measurement of its weight. When a diamond is properly cut, the carat weight defines the size of the diamond, and larger diamonds tend to be more expensive. Ada Diamonds offers lab grown diamonds as small as  0.01ct to over 5ct in a variety of shapes.
