The Four Cs

Every diamond is specified by four measures. Understanding them is the difference between buying a stone and choosing one. Here is how we read each.

Carat

Weight

Carat is weight, not size — one carat is 0.20 grams, measured to the hundredth. Two diamonds of equal carat can look different depending on how the weight is distributed and cut. Our pieces range from a 0.20 ct huggie to a 20 ct tennis bracelet.

Color

D — Z

Color grades how near to colorless a diamond is. D is exceptional white; the further down the alphabet, the warmer the tint. Our stones are graded from D–E (colorless) through F–G (near-colorless) — the range where rarity meets value.

Clarity

FL — I

Clarity measures the tiny inclusions formed in a diamond's growth. VVS (very, very slightly included) is nearly flawless to the eye; VS and SI remain eye-clean in most settings. We publish the clarity of every stone so there are no surprises.

Cut

The fire

Cut is craft — the proportions and symmetry that decide how much light a diamond returns. A well-cut round brilliant gathers light and throws it back as fire and sparkle. It is the C you see before any other.
