Buying guide

Why the round cut is the classic choice

The round brilliant is cut with many facets arranged to return as much light as possible, which is why it shows more sparkle than any other shape. Its outline is symmetrical, so it suits every setting style, and its brilliance helps hide small inclusions and a hint of color. A round engagement ring does not follow trends, which makes it a safe choice for a ring you plan to wear for life.

Picking a setting for a round center

  • Solitaire: a single round center on a plain band, held by prongs or a bezel.
  • Halo and hidden halo: a ring of lab-grown diamond accents around or below the center makes it look larger.
  • Pavé and side stone: lab-grown diamond accents along the band, from fine pavé to marquise and baguette side stones.
  • Three stone: the center flanked by two smaller stones.
  • Vintage: milgrain, filigree and floral details.

Metal, karat and price

Every setting comes in white, yellow or rose gold, in 10K, 14K or 18K. White gold makes a colorless center look its whitest, while yellow and rose gold add warmth. Settings start from about $500, and most are between about $1,000 and $1,300. That is the price of the setting alone; the center is priced when you choose it in the next step.

Round Engagement Rings FAQs

What setting is best for a round diamond?

A prong setting is the most popular for a round diamond, because it lets the most light into the stone and shows off its sparkle. Six prongs add security, while four prongs show more of the stone. A bezel is the most protective choice for an active life, and a halo makes the center look larger. Solitaire, pavé, halo and bezel settings are all in this collection.

Is a round engagement ring a good idea?

Yes. The round cut is the most popular engagement ring shape because it has the most sparkle and suits every setting style. It does not follow trends, so it will not look outdated, and it has no sharp corners to chip. The trade-off is price: a round stone usually costs more per carat than fancy shapes of similar quality.

Which is more expensive, round or princess cut diamond?

A round diamond usually costs more than a princess cut of the same carat weight and quality. Cutting a round brilliant from a rough crystal wastes more material, and demand for rounds is higher. A princess cut keeps more of the rough, so it often costs noticeably less per carat. The settings on this page are priced on their own, and you see the center's price when you choose it.

What looks bigger, round or cushion cut?

A round usually looks bigger than a cushion of the same carat weight. A round brilliant spreads more of its weight across the top, while many cushions carry more weight in their depth. A princess cut also faces up smaller than a round of the same weight, because its corners hold weight. A halo setting, found on many designs here, makes a round center look larger still.
