Round, oval, cushion, emerald — the shape of your diamond defines the entire personality of the piece. Here's what each shape says, who it suits, and what to watch for.
Round Brilliant — The Timeless Classic
The most popular shape for a reason: 58 precisely angled facets return more light than any other cut, giving unmatched fire and brilliance. Round diamonds also hide inclusions and color best, so you can save with slightly lower clarity and color grades. Choose it if: you want maximum sparkle and timeless appeal. Browse round engagement rings.
Oval — Elegant and Flattering
An elongated brilliant cut that looks larger per carat than a round — a 1-carat oval can face up like a 1.2-carat round. Its length flatters the finger beautifully. Watch for the "bow-tie effect" (a dark band across the center); a well-cut oval minimizes it. Choose it if: you want presence, elegance, and value.
Cushion — Vintage Romance
Soft rounded corners with large facets — romantic, vintage-inspired, and incredibly fiery. Cushions hide inclusions well but can show color, so consider G or better. Choose it if: you love antique style with modern brilliance.
Emerald — Understated Luxury
Long step-cut facets create a "hall of mirrors" effect — sophisticated flashes of light rather than disco-ball sparkle. The large open table shows everything, so prioritize high clarity (VS2+) and color. Choose it if: your style is refined and understated.
Princess — Modern Edge
Square with brilliant faceting — contemporary, sharp, and very sparkly. Great brilliance per dollar. The pointed corners need protective prongs. Choose it if: you want modern geometry with serious fire.
Pear and Marquise — Distinctive
Elongated fancy shapes with tons of personality — and excellent value, since less rough is wasted in cutting. Both maximize finger coverage per carat. Choose them if: you want something nobody else has.
