Diamond Shapes

Ten classic silhouettes

The shape is what you see first. Each silhouette has its own personality — and its own price-per-carat. Round brilliants are the most popular and the most expensive per carat; fancy shapes (oval, pear, emerald) can give you a visibly larger stone for the same budget.

The 4 Cs · in plain English

What actually decides a diamond's value

  • C1

    Cut

    How well the diamond is faceted. Cut = sparkle. A well-cut stone is brighter than a bigger, poorly-cut one.

  • C2

    Colour

    Graded D (icy white) to Z (warm yellow). For white diamonds, closer to D is more prized.

  • C3

    Clarity

    How clean it is inside. FL/IF are flawless; VVS, VS and SI are common and look beautiful to the eye.

  • C4

    Carat

    The weight, not the size. 1 carat = 0.2 grams. Two diamonds of the same carat can look different sizes depending on cut.
