Marquise VS1 Clarity Lab Grown Diamonds
Discover marquise VS1 clarity lab grown diamonds hand-selected for brilliance, every stone graded by IGI and priced well below mined diamonds. Choose from 40 options from 1 to 10 carats, in D, E and F color and VS1 clarity, priced from $304.
About the marquise shape
The marquise is a long, boat-shaped brilliant with two points that gives the largest look per carat. It is one of the most requested shapes for engagement rings and works with solitaire, halo, hidden halo and side stone settings.
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. Carat weights range from 1 to 10 carats. Prices in this collection range from $304 to $112,219.
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.
Why buy from Northfire Jewelry
Every diamond is IGI certified, shipped free and fully insured within the USA, and backed by a 30-day return policy. Lab grown diamonds are real diamonds, chemically, physically and optically identical to mined diamonds, at a fraction of the price. Our team can set your diamond in any of our engagement ring designs or create a fully custom ring for you.
