About the square shape

The square is a distinctive square 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.

What does D color mean?

D is the highest color grade on the GIA/IGI scale. A D color diamond is completely colorless, with no trace of warmth even when viewed face-down under laboratory lighting.

How to choose

VVS1 and VVS2 are the cleanest grades we offer, while VS1 and VS2 are eye-clean and leave more budget for carat weight. Carat weights range from 1 to 3.5 carats. Prices in this collection range from $1,209 to $2,365.

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.

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.
