A contemporary three-stone ring from circa 1990, centered on a natural purple sapphire from the Himalaya mountain— one of the rarest and most compelling color sapphires available to collectors today. Clean, confident, and built to be worn.
The sapphire weighs 3.79 carats and displays the characteristic deep, saturated purple that distinguishes Himalayan sapphires from all other sources. The stone is accompanied by a certificate from GRS (Gemresearch Swisslab) confirming the origin and no thermal treatment.
The sapphire is flanked by two oval brilliant-cut diamonds in a classic three-stone composition. The 18k white gold shank is set throughout with brilliant-cut diamonds, bringing the total diamond weight to approximately 0.80 carats.
