How big is a 1 carat diamond?

Carat measures weight, not size, but weight decides how large a diamond looks. A 1 carat round diamond measures about 6.5 mm across. 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.

What does VS1 clarity mean?

VS1 (Very Slightly Included 1) diamonds have minor inclusions that are difficult to see under 10x magnification. They are eye-clean and a favorite for engagement rings.

How to choose

For a bright, icy look choose D or E color; F color gives the best value while still appearing colorless. Available shapes include Round, Oval, Cushion, Pear, Emerald, Princess, Heart and Marquise and more. Prices in this collection range from $267 to $17,237.

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.
