Art Deco Star Sapphire & Diamond Platinum Ring, 36ct, Circa 1930s

A 36 carat oval cabochon star sapphire commands this substantial Art Deco ring, its grayish-blue body showing the soft, cloudy translucence characteristic of asterism-producing corundum; the fine silk inclusions that scatter light into a six-rayed star under direct illumination, though the effect is best seen in person or under a single point light source rather than in photographs. Old European, single round, and pear brilliant diamonds frame the stone, 1.25 carats total in H-I color and SI1 clarity, their faceted sparkle providing contrast to the sapphire's smooth, domed surface. The platinum setting holds the stone high with a substantial gallery, a mounting style period jewelers used specifically to let light reach large cabochons from multiple angles. At 19 x 22mm across the top and 16 grams total, this reads as a genuine statement piece rather than an everyday ring. Condition is excellent for its age: the platinum retains a bright, well-kept finish, and the sapphire shows no visible chips or surface damage.
