Diamond Cuts Explained: Choosing the Perfect Shape for Your Ring

Diamond cuts control how a stone returns light and how it reads on the hand. This guide explains popular diamond cuts and diamond shapes (round, princess, emerald, cushion and more), how they affect sparkle and wear, and which cuts suit which personalities and lifestyles.

What “cut” actually means

“Cut” describes proportions, facets, symmetry and polish — the workmanship that determines brightness, fire and scintillation. A well-cut stone reflects light back to the eye; a poorly cut stone loses light. If sparkle is your priority, cut is the single most important C.

Quick shape guide (what each says about the wearer)

  • Round Brilliant — maximum fire and classic confidence; forgiving and versatile.
  • Princess — square, contemporary, a little architectural; suits modern minimalists.
  • Emerald/Asscher — step cuts with a “hall of mirrors” look; great for clarity lovers and those drawn to vintage restraint.
  • Oval/Pear/Marquise — elongating shapes that visually lengthen the finger and read elegant or dramatic.
  • Cushion/Radiant — soft corners, great when you want a vintage-meets-modern feel.

Practical matching (cut to setting & lifestyle)

  • Active hands: choose bezel or low-set solitaire for protection.
  • Prioritise cut over colour/car at if sparkle matters most.
  • Try shapes in person — the same carat can look very different depending on table and length-to-width ratio. Use our in-store trials to compare.


How we help in-store


We show identical stones in different cuts to demonstrate brilliance differences and advise which cuts suit your hand and everyday life. For more on the technical side see GIA’s 4Cs resources.
