About the Item

Vintage Gübelin Royal Blue Sapphire and Diamond Platinum & Gold Ring An exceptional vintage jewel by Gübelin, Switzerland, circa 1990, showcasing a large untreated Royal Blue sapphire accented by fine white diamonds, mounted in platinum and 18 karat yellow gold. At the center sits a mesmerizing oval sapphire weighing 10.98 carats, measuring 14.5 x 10.7 x 6.7 mm. The stone displays an impeccable VVS clarity and an extraordinary Royal Blue color, prong-set in yellow gold. Originating from Sri Lanka (Ceylon), the sapphire is certified by GCS London Gem Lab as completely untreated, with no evidence of heat or enhancements—a hallmark of Gübelin’s finest creations. Under light and magnification, the stone reveals delicate rutile silk inclusions and velvety zoning that impart a rare, almost Kashmir-like Tyndall effect, leading us to recommend a second gemological opinion for possible Burma origin. Flanking the sapphire are two trillion-cut diamonds, each approximately 1.00 carat (total diamond weight approx. 2.00 carats). Graded H color, one diamond shows VVS2 clarity while the other falls in the VS2 range, both adding brilliance and balance to the vivid sapphire. The ring is beautifully crafted in Pt950 platinum and 18K yellow gold, hallmarked accordingly and signed with Gübelin’s maker’s mark inside the shank. Ring size 7
