Estate 18K Sugarloaf Cabochon Rubellite Tourmaline Diamond Dome Cocktail Ring

A bold, sculptural cocktail ring crafted in substantial 18 karat yellow gold, centered by an impressive approximately 20 carat custom-cut modified sugarloaf cabochon tourmaline with a rich rubellite-red to raspberry-pink glow. The stone’s high-domed, softly peaked form gives the ring tremendous presence, framed by a raised polished gold bezel that contrasts beautifully against the satin-finished gold shoulders. An internal inclusion is visible near one corner of the tourmaline, as shown, but it remains contained within the stone and does not reach the surface. Carved fluted detailing and round brilliant diamond accents add dimension and light while preserving the ring’s strong, luxurious silhouette. Substantial, confident, and beautifully made, this is a statement jewel with real presence on the hand.
