6.43 Carat No-Heat Tajikistan Ruby and Diamond Ring in Platinum

This magnificent cushion-shaped ruby weighing 6.43 carats—measuring 11.30 x 10.45 x 5.80 mm—originates from the storied mines of Tajikistan, renowned for producing rubies of exceptional depth and fire. Displaying a captivating, transparent crimson hue, the stone is certified by AGL, C. Dunaigre, and GIA as natural and unheated, affirming its rarity and prestige in the world of fine gemstones. Encircled by a halo of finely matched brilliant-cut diamonds weighing a total of 2.00 carats, the ruby is elegantly mounted in handcrafted platinum, elevating its brilliance while offering timeless sophistication. The marriage of noble platinum, natural diamonds, and a no-heat Tajikistan ruby positions this jewel among the most coveted treasures of high jewelry. Such examples, particularly of Tajikistan origin and free from heat treatment, seldom appear on the international market. This ring represents an opportunity for collectors and connoisseurs to acquire a stone of distinguished provenance, unrivaled transparency, and regal allure.
