Tiffany diamonds are always cut to maximize brilliance, not carat weight. “Carat” denotes the weight of a diamond.
One carat equals .20 grams. Tiffany measures diamonds to 1/1000th of a carat. Taken by itself, carat weight does not determine a diamond’s value. For example, two one-carat stones can vary widely in price when clarity, color and cut are taken into consideration. When that is understood, it is clear that large diamonds of peerless quality are rare and priced accordingly.
The gemological standards in this guide refer only to round brilliant diamonds from .18 to 2.99 carats set in certain ring styles. Round brilliant diamonds smaller or larger, fancy-shaped diamonds and fancy color diamonds each have their own specially tailored standards of evaluation. Consult your Tiffany Sales Professional for details.
