If you're looking to buy a radiant-cut diamond, you have several good options online and in the Miami area. Radiant cuts have a rectangular or square shape with trimmed corners and brilliant-style facets, giving them lots of sparkle.
I'd start by comparing loose diamonds first, so you can choose the stone before deciding on a ring setting.

How to choose the right radiant diamond
- Carat: Compare 1.5, 2, 3 carats or larger, depending on your budget.
- Color: G–H can offer a good balance of appearance and price; D–F are closer to colorless.
- Clarity: VS1 or VS2 is a useful starting point, but inspect the actual stone.
- Shape: Compare elongated rectangular radiants with squarer ones.
- Certification: Verify the individual stone's grading report and inspect its video for light performance and dark areas.
Let me narrow it down for you

- Ratio & Shape: Radiant cuts come in both square (ratio of 1.00 to 1.05) and elongated (ratio of 1.15 to 1.30+) profiles. Decide whether you prefer a squarish look or a longer, finger-flattering shape.
- Bow-Tie Effect: Like many modified brilliant cuts, radiant cuts can occasionally display a dark bow-tie shadow across the center. Inspect high-definition videos or view the stone in person.
- Clarity vs. Brilliance: Because of the brilliant-cut faceting pattern (often called a "crushed-ice" look), radiant cuts are very effective at hiding minor inclusions. An SI1 or VS2 clarity grade often offers the best value without visible flaws to the naked eye.
- Certification: Ensure the diamond comes with an independent grading report from an accredited lab such as the GIA (Gemological Institute of America) or IGI (International Gemological Institute).
Are you looking for a natural or lab-grown radiant cut diamond, and do you have a target carat size, budget, or preferred shape (square vs. elongated) in mind?
