Art Nouveau 4.60 Carat Natural Ceylon Sapphire & Rose Cut Diamond Ring, French, circa 1900

The blue in this natural Ceylon sapphire ring is just about perfect. The bright, rich gemstone – certified as natural and with no indications of heating – displays glowing cornflower hue. Fourteen rose cut diamonds are rubover set in the silver surround, with stunning scroll detailing in the under-gallery. On a slim, rose gold shank. So utterly beautiful.
