Vintage GIA 2.51 carat old mine cushion cut diamond 18k white gold ring

There is a softness to old mine cut diamonds that modern brilliants simply cannot replicate, and this 2.51-carat cushion example is a beautiful case study. Cut by hand in an era before precision faceting machines, its high crown and open culet were designed to catch candlelight and lamplight alike, throwing broad, warm flashes rather than the sharp pinpoint sparkle of a contemporary round brilliant. GIA has certified the stone at I color and SI1 clarity, confirming both its size and its clean, eye-pleasing face-up character.

Set in 18k white gold and dating to circa 1970, the ring pairs old-world diamond cutting with a clean, wearable mounting that reads as quietly substantial rather than showy. At 11.14 grams, it has real presence on the hand without feeling heavy or dated. Currently sized 4.25, it can be sized to fit.

This is a ring for someone drawn to the romance of estate diamonds: a solitaire with a story already written into its facets, ready to become the centerpiece of an engagement, an anniversary gift, or simply a exceptional diamond acquired for its own sake.
