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.
Want to see them rather than read them? The buying guide draws every carat size, colour grade and clarity grade to scale.
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 4 ct solitaire engagement ring.
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.
