Reading a stone card

Specs that matter most.

Cut

Determines whether a stone looks alive. Carat lists Ideal and Excellent only.

Color

D–F is colorless. G is the practical floor for round and oval. F or better for emerald.

Clarity

VS2 is eye-clean in most settings. Push to VVS for step-cuts.

Carat threshold

Prices step up at 1.0, 1.5, 2.0. A 1.45ct often looks identical to a 1.52ct for ten percent less.
