Important one-of-a-kind 23-carat Ceylon natural no-heat sapphire and diamond convertible necklace/brooch in platinum and White gold, Portuguese, circa 1957, crafted for an occasion graced by Queen Elizabeth II during her royal visit to Lisbon, accompanied by a custom-fitted case. This exceptional and singular vintage jewel hails from the 1950s, an era of unrivaled elegance and exquisite craftsmanship. It boasts a transformative centerpiece crafted as a convertible necklace-brooch of unparalleled artistry. At its heart lies a resplendent round-shape natural Ceylon sapphire, a dazzling gem of remarkable rarity, weighing a remarkable 23.01 carats. The centerpiece is an exquisite focal point, a dazzling spectacle adorned with a stylized floral cluster delicately adorned with round brilliant-cut and marquise brilliant-cut diamonds, further accentuated by smaller oval-shape sapphires. This captivating cluster extends gracefully on either side, adorned with delicate swags of alternating marquise brilliant-cut diamonds and oval-shape sapphires, culminating in a sublime sapphire and diamond cluster terminal, which transitions seamlessly into an articulated link necklace meticulously set with diamonds throughout. The versatility of this Mid-Century jewel is underscored by its capability to transform into a striking brooch, secured with a click-shut and safety catch fitting, further augmented by a hinged pin brooch fitting. The exceptional 23-carat Ceylon sapphire stands as a testament to its rarity. Natural, non-heated sapphires of this caliber, especially surpassing 5 carats, are extraordinarily rare and highly sought-after, adding unparalleled allure and value to this piece.
