Presenting an extraordinary, museum-grade treasure: a monumental 120.00 Carat Natural Unheated Burma Blue Sapphire. Originating from the world-renowned mines of Myanmar (Burma), reaching a 120-carat weight class while remaining 100% untouched by heat or enhancement is a gemological marvel reserved for elite global collections.
Masterfully faceted into an elegant oval shape with excellent proportions and optical symmetry, this stone yields magnificent face-up light refraction, velvety body color, and vivid royal blue brilliance. Graded as Slight VVS clarity, it achieves exceptional visual transparency—an exceedingly rare quality standard for an untreated natural blue corundum of such immense scale.
Dual-certified by two of the world's most authoritative premier gemological institutes, GRS and SSEF, confirming both its unheated status and legendary Burmese origin. An ideal centerpiece for sovereign collections, institutional portfolios, or bespoke high-jewelry commissions.
