Crafted by the legendary Tiffany & Co., this enchanting necklace is a rare and unique masterpiece of early 20th-century American jewelry design. Delicately handcrafted, the one-of-a-kind creation is set with two stunning examples of Kashmir sapphires weighing 5.65 and 4.60 respectively. These gemstones are certified by the American Gemological Laboratories as Kashmir in origin and completely untreated, an extreme rarity for Kashmirs. Dozens of sparkling white diamond accents complement the brilliant blue stones in a romantic, winding 18K yellow gold setting. These incredible sapphires would have been sourced by George Frederick Kunz, Tiffany & Co.'s expert gemologist, who selected only the finest gemstones for the firm's unique creations. The sapphires in this necklace are truly superior examples. Kashmir sapphires were first unearthed in the early 1880s after a landslide in the northwestern region of the Indian subcontinent. They are celebrated not only for their rarity, but also for the softness of their distinctive blue hue. Boasting incredible color and brilliance, untreated Kashmir sapphires of this quality are scarce, especially within an antique Tiffany setting. Since the firm's inception in 1837, Tiffany & Co. has been at the forefront of luxurious design and craftsmanship, especially in the realm of fine jewelry. Founder Charles Lewis Tiffany...
