The brilliant benchmark

The round brilliant is the most researched diamond cut, with 57 or 58 facets designed for maximum brightness. It is the most versatile shape for rings, studs and pendants.

Buying tips

Cut is the key grade for rounds: choose Excellent or Ideal. Because rounds hide color and inclusions well, G color and VS2 clarity often look as good as higher grades for less money.

About the round shape

The round is the most brilliant diamond shape, cut with 57 facets to return the maximum amount of light and sparkle. It is one of the most requested shapes for engagement rings and works with solitaire, halo, hidden halo and side stone settings.

Choosing a round diamond

Start with carat weight to set the size, then balance color and clarity against your budget. D and E colors look icy white, while F color is the best value in the colorless range. VVS1 and VVS2 are the cleanest grades we stock; VS1 and VS2 are eye-clean and let you choose a larger stone for the same price. Prices for round diamonds in our collection range from $273 to $31,826.

Lab grown vs mined diamonds

Lab grown diamonds are real diamonds with the same chemical structure, hardness and sparkle as mined diamonds, graded on the same scales by IGI. They cost a fraction of the price and have a known, conflict-free origin, so you can choose a bigger or better round diamond for the same budget.

Setting your round diamond

Our jewelers can set your diamond in a solitaire, hidden halo, halo, side stone or three stone engagement ring in white, yellow or rose gold or platinum, or create a fully custom design. Every ring is made to order and approved by you before it ships.

Why buy from Northfire Jewelry

Every diamond comes with its IGI grading report, free insured USA shipping and a 30-day return policy, and our team is here to help you compare stones and choose the right one.
