One of the most important (and most fun!) decisions? Choosing the best diamond shape for your engagement ring. From classic round brilliants to bold marquise cuts, each shape has its personality, sparkle, and symbolism.

The most popular diamond shapes include:

• Round Brilliant

• Oval

• Princess (Square)

• Cushion

• Emerald

• Pear

• Marquise

• Radiant

• Asscher

• Heart

Things to Consider Before You Decide

• Your Lifestyle

Active lifestyle? Go for smoother shapes like oval, round, or cushion. They’re less likely to snag.

• Your Personal Style

Are you drawn to bold, vintage, minimalist, or classic fashion? Let your style lead the way.

Some shapes (like round and princess) cost more per carat than others. You can get a larger-looking stone for less with ovals or marquise cuts.
