Color

Color

Diamond color measures the subtle tint present in a diamond. Learn how the D–Z color scale works, what color grades look white to the eye, and how Ada Diamonds evaluates lab diamonds for brightness and undesirable color undertones.

Diamond Education

Clarity

Clarity

Clarity is a measurement of how many or how large of blemishes or inclusions are present in the diamond. The lower the clarity of a diamond, the more imperfections in the diamond. Lab diamonds vary in clarity, just like mined diamonds.

Diamond Education

Carat

Carat

Carat weight measures how much a diamond weighs, not how large it appears. Learn how carat weight influences a diamond’s size, rarity, and price, and how Ada Diamonds helps clients find the right balance of beauty, proportions, and value.
