Qty:
This extraordinary ring is centered on an 8.07-carat oval cut Burmese sapphire of exceptional quality, renowned for its vivid royal blue hue and impressive untreated status. The sapphire is accompanied by grading reports from GRS, Dunaigre and Gubelin, which confirm the gem’s prestigious Burmese origin and natural, unheated condition. Flanking the sapphire are two half-moon diamonds, totaling 1.16 carats, with G color and SI1 clarity. Together, they enhance the ring's brilliance and elegance. Set in platinum and 18K yellow gold.

Large sapphires like this are among the scarcest treasures in nature. Their formation deep within the earth requires not only a precise mineralogical balance but also the perfect combination of geological conditions, pressure and temperature. Additionally, the presence of rare chemical elements such as aluminum, iron and titanium is essential. In contrast, modern heating and chemical enhancement methods have become prevalent, mimicking the qualities of untreated sapphires. The demand for natural, unheated sapphires continues to grow, but their limited supply—especially from esteemed sources like Burma—makes them exceedingly rare and sought after by collectors.
