Condition Notes: An exceptional opportunity to reimagine a vintage Harry Winston semi-mount into a custom masterpiece, this platinum ring offers a four-prong central setting currently measuring approximately 14.00 x 13.00 mm, ready to receive a significant gemstone of your choosing. Flanking the open center are calf's head–shaped diamonds that exhibit a gently warm tone, providing a subtle contrast against the cool luster of the platinum. The mounting displays a delicate patina from careful prior wear, with slight discoloration at the base of the shank indicating a past resizing. The ring is stamped "HANDMADE PB 10% IRID PLAT" and the Harry Winston logo hand-inscribed inside the shank.
Harry Winston: An ambitious man, Harry Winston parlayed a $2,000 investment into what is arguably regarded as the best diamond jewelry business of the 20th century. The 5th ave location opened in March 1960, Harry incorporated in 1932. Harry Winston was renown for his ability to see the potential locked within a diamond. He often purchased jewelry solely for the purpose re-cutting major diamonds. He is famous for cutting many of the world’s most spectacular diamonds, such as the Jonker and the Taylor-Burton. Winston donated three very famous diamonds to the Smithsonian museum: the Oppenheimer, the Hope, and the Portuguese. Often referred to as the "King of the Diamonds", he owned one-third of the world's most famous diamonds at one time. Harry Winston died in 1978. The business continues to operate select cities across the U.S. and abroad. Among the many variations of identifiable WINSTON and HW maker’s marks, two other maker’s marks are widely seen on their jewelry. The Swiss Francios Tavernier mark is dated to 1942 through the mid-1960s. The Jacques Timey mark, also Swiss, was established in 1966 and used through the early 2000s.
