How big is a 3 carat diamond?

Carat measures weight, not size, but weight decides how large a diamond looks. A 3 carat round diamond measures about 9.3 mm across, and a 3 carat extra elongated radiant will have a similar face-up area spread over its own outline. Fancy shapes such as oval, pear and marquise often look larger than a round of the same weight because more of their weight sits in the visible top of the stone.

About the extra elongated radiant shape

The extra elongated radiant is a distinctive extra elongated radiant cut chosen by buyers who want a one-of-a-kind look. Because it is less common than classic shapes, it gives a ring or pendant a look that stands out.

How to choose

For a bright, icy look choose D or E color; F color gives the best value while still appearing colorless. VVS1 and VVS2 are the cleanest grades we offer, while VS1 and VS2 are eye-clean and leave more budget for carat weight. Prices in this collection range from $1,049 to $2,450.

Are lab grown diamonds a smart choice?

Lab grown diamonds are real diamonds with the same chemical makeup, hardness and sparkle as mined stones, so they are just as durable for everyday wear. Because they cost a fraction of the price, many couples choose a larger carat weight or a higher color and clarity grade for the same budget, and they enjoy a known, ethical origin.

Setting your diamond

Once you pick a stone, our jewelers can set it in a solitaire, hidden halo, halo, pavé or three stone engagement ring in 14K or 18K white, yellow or rose gold or platinum. Each ring is made to order, and our team will confirm sizing and proportions before production.
