Provenance
Original to c.1905, this Edwardian era ring is set to centre with a cushion shape old-mine cut diamond with an approximate weight of 0.35ct. Beautifully balanced and thoughtfully proportioned, it embodies everything a classic solitaire should be - refined, timeless and effortlessly wearable.
The old-mine cut is one of the earliest diamond cuts. Sourced from the historic mines of India or Brazil (the world’s first known diamond deposits) these stones possess a character impossible to replicate today. Their softly rounded cushion outline, born from hand-cutting rather than modern laser machines, gives them a romantic glow and gentle fire far removed from the sharper brilliance of modern-cut diamonds.
The diamond is elegantly claw-set in an open-back setting in platinum, a stronger metal than gold which had the advantage of complimenting the bright white glow of the diamond it holds. The gallery is intricately pierced in a linear motif and the shoulders are solid, lightly raised and taper gently to a solid 18ct yellow gold band.
