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 better half of near-colorless (G, H) and refuses to sell any inferior color diamonds.

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 Slightly Included or better.

Carat Weight

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).
