Taylor's "Love Story" Ring

T Swift is engaged! And her Old Mine Cut diamond is making news. Here’s what it means:

Old Mine Cut

  • Shape: Squarish to cushion-like with rounded corners.

  • Facet Style: Brilliant cut precursor – larger facets, high crown, small table, and deep pavilion with a large open culet (flat facet at the bottom).

  • Look: Romantic, soft, and warm sparkle; less precise symmetry compared to modern cuts, with a "glow by candlelight" quality.

  • Era: Popular from the 1700s to late 1800s, before the round brilliant was perfected.

  • Best Features: Antique charm, hand-cut individuality, unique play of light.

vs.

Emerald Cut

  • Shape: Rectangular (sometimes square) with long step-cut facets and cropped (cut-off) corners.

  • Facet Style: Step cut – broad, flat planes that look like "steps" going into the stone.

  • Look: Elegant, hall-of-mirrors effect with flashes of light rather than sparkle.

  • Era: Became popular in the 1920s–1930s Art Deco period, and remains a modern classic.

  • Best Features: Shows off clarity and color of the stone; sleek, understated, geometric.

Emerald cut = modern, rectangular, step-cut elegance.

Old mine cut = antique, cushiony, hand-cut brilliance with a vintage glow.
