Round Cut Diamond FAQs

Why is the round-cut diamond the most popular choice?

The round cut is classic and timeless—and because of that popularity, you’ll find a wide range of choices on the market. The round brilliant cut’s many facets (57 or 58) are optimized to return lots of light, giving maximum sparkle.

If I’m on a budget, can I still get a good-looking diamond by choosing slightly lower color or clarity in a round cut?

Often yes—because round cuts reflect light so well, many “near-colorless” or moderately included stones still look clean to the eye. As long as the cut is good and inclusions aren’t in obvious spots, you can find a nice balance between value and appearance.

Why are round diamonds more expensive than other shapes?

That’s because they’re in very high demand, and you lose more rough diamond material when cutting a round stone (so there’s more waste).
