What cut is Taylor Swift's diamond?

Old Mine and Old European cuts are antique diamond styles from the 1700s and 1800s, hand-shaped before precision faceting machinery existed. They tend to have a higher crown, a smaller table, a large culet and a softer, warmer sparkle than modern round brilliants. Taylor Swift's stone is the elongated version, which reads more like a soft cushion than a round. The look is romantic and vintage rather than the crisp, white-light brilliance of a modern hearts and arrows round.

Cushion cuts and their antique variants are one of the fastest-growing shapes in engagement rings, alongside ovals and emerald cuts. They sit between a round and a princess in outline, with softly rounded corners that read both classic and modern. A high-profile celebrity ring tends to lift its shape for a couple of years, and cushion is the current beneficiary. Cushion still reads as less common than round on the average hand, which is part of the appeal for many buyers.
