From Emilio Jewelry New York, An exceptional and rare 6.15 carat natural Kashmir sapphire, displaying a richly saturated cornflower royal blue color and remarkable transparency, set in a refined signed Bulgari platinum diamond ring. Important Kashmir sapphires of this caliber are rarely offered publicly and are typically placed directly into long-term private collections. This stone has that alive, glowing, velvety royal blue that no other origin can replicate. This Kashmir is unlike any other. A superb Royal Blue Kashmir sapphire of exceptional saturation and tone, exhibiting the coveted velvety texture and soft luminosity that define the finest stones from this legendary origin. The sapphire has been confirmed as Kashmir origin with no indications of heat by three of the world’s most respected gemological laboratories: American Gemological Laboratories (AGL), SSEF Swiss Gemological Institute, and Gübelin Gem Lab. What many consumers don’t know is that for a Kashmir sapphire to be considered a Top Stone it must be certified by all 3 laboratories ssef, Gubelin, and AGL. Many Kashmir sapphires only have one certificate or none of the above labs which means its value is a fraction of a Kashmir with the 3 labs mentioned above. Kashmir sapphires are widely regarded as the most desirable sapphires in the world, celebrated for their distinctive velvety blue color and exceptional rarity. Stones exceeding five carats with confirmed Kashmir origin and no heat treatment are extraordinarily scarce. This sapphire possesses the qualities collectors seek most: a vivid royal blue hue, excellent brilliance, and outstanding clarity. The stone is loop clean, a rare characteristic for Kashmir sapphires of this size. Gübelin has further awarded the gemstone an Exceptional Gemstone Rating of 88, a distinction reserved for stones of superior quality and beauty. The sapphire is elegantly mounted in a signed Bulgari platinum ring, accented by emerald-cut diamond side stones that frame the center gemstone while maintaining a timeless and sophisticated design. Important Kashmir sapphires of this caliber are rarely offered publicly and are typically placed directly into long-term private collections. A remarkable opportunity to acquire a museum-worthy natural Kashmir sapphire of significant size, provenance, and rarity. Private viewings are available by appointment. ⸻ Details Center Stone: Natural Sapphire Origin: Kashmir Weight: 6.15 carats Treatment: No indications of heat Shape: Cushion mixed cut Color: Royal Blue Certification • American Gemological Laboratories (AGL) • SSEF Swiss Gemological Institute • Gübelin Gem Lab Mounting • Signed Bulgari • Platinum • Emerald-cut diamond side stones Serious inquiries are invited for this exceptional Kashmir sapphire.
