Tiffany & Co.'s Fleur de Lis Diamond Key Pendant

This is a Tiffany & Co.'s Fleur de Lis Diamond Key Pendant, crafted from '750' purity gold, commonly interpreted as 18-karat gold, and adorned with numerous round brilliant-cut diamonds. The key design features a stylized Fleur de Lis motif at its bow (the top, ornamental part of the key), which is intricately detailed with a combination of pave-set and bezel-set diamonds. The central part of the bow showcases a cluster of diamonds forming a floral or star-like pattern, surrounded by an openwork, curvilinear design also encrusted with diamonds. The stem or shaft of the key is straight and appears to be fully pave-set with diamonds along its length, creating a continuous sparkling surface. The bit (the part of the key that enters the lock) is a distinctive trefoil or clover-like shape, also set with diamonds. A bail, likely also of 18k gold, is attached to the top of the bow for suspension on a chain. The overall color is a bright white metal, indicative of white gold or platinum, though the '750' marking confirms it as 18k gold. The item appears to be in excellent condition with no visible damage, missing stones, or significant wear, maintaining its brilliant luster. The craftsmanship is high-quality, characterized by precise diamond setting and a well-finished metal surface. Based on the presence of the 'Tiffany & Co.' and '750' markings, it is an authentic piece from the renowned jewelry house, likely a contemporary design from their popular 'Tiffany Keys' collection. Its aesthetic combines classic elegance with modern sparkle.
