Vintage Platinum Cabochon Star Sapphire Baguette Round Diamond Cocktail Ring
A striking vintage cocktail ring crafted in platinum, centered by a dramatic cabochon star sapphire weighing approximately 13.00 carats. The sapphire displays a rich purplish-blue body color and a beautifully defined six-ray star, an optical phenomenon caused by intact rutile silk and indicative of no heat treatment. The bold center stone is elegantly framed by a combination of tapered baguette and round diamonds, adding brilliance and architectural balance to this substantial and collectible design.
