Choosing the right diamond shape depends on your style, budget and how the stone looks on your hand. Round brilliant cuts are timeless and sparkly, but fancy shapes like princess, oval, cushion, emerald and pear offer unique looks and better value for the same carat weight.
Most popular diamond shapes:
- Round brilliant – classic and fiery; most expensive per carat
- Princess – modern square with great sparkle
- Oval – elegant and elongating, looks larger than a round
- Cushion – romantic rounded square with vintage feel
- Emerald – sleek rectangular step cut highlighting clarity
- Pear – teardrop shape blending round and marquise
What to consider when choosing:
- Finger shape and size – elongated shapes slim and lengthen fingers
- Setting style – halos make stones appear larger
- Budget – fancy shapes often cost less per carat than rounds
