A princess-cut diamond ring in platinum — bright, clean, made to last.
Platinum never fades, never needs replating, and holds stones more securely than any gold alloy. The choice when nothing should compromise the piece.
Diamonds channel-set into the band — secure, flush, no prongs to catch.
Diamond carries the brightest light in stone — the standard against which every other gemstone is measured. Reflects fire in every direction.
Stacks with simple bands or wears solo — the proportions allow either.
