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.
