How big is a 10 carat diamond?

Carat measures weight, not size, but weight decides how large a diamond looks. A 10 carat round diamond measures about 13.9 mm across, and a 10 carat cushion 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 cushion shape

The cushion is a square or rectangular brilliant with soft rounded corners and a romantic, pillow-like outline. It is one of the most requested shapes for engagement rings and works with solitaire, halo, hidden halo and side stone settings.

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 $3,235 to $14,879.

Lab grown vs mined diamonds

A lab grown diamond is created in a controlled environment that recreates the heat and pressure under which natural diamonds form. The result has the same crystal structure, hardness of 10 on the Mohs scale, fire and brilliance as a mined diamond, and it is graded on the same color, clarity and carat scales. The main differences are price, which is typically 70 to 90 percent lower, and a traceable, conflict-free origin.

From loose diamond to finished ring

Pair your diamond with any Northfire setting, from a sleek solitaire to a pavé halo, in white, yellow or rose gold. We handcraft every ring to order and send photos for approval, so your diamond and setting are matched perfectly before the ring ships.
