Harry Winston

Harry Winston immigrated to the United States from Ukraine during the early 20th century, and grew up working in his father's jewellery shop. At the young age of twelve, his innate talents revealed his natural understanding of gemstones and the ability as a gemmologist. Consequently, it led to his success in stone-dealings, which assisted him to establish his own business at the age of only twenty-four.
The Winston jewellery empire really began in 1926, with Harry's acquisition of a very important private jewellery estate – the Arabella Huntington collection. Mrs Huntington, the wife of the railroad magnate Mr Henry E. Huntington, assembled one of the world's most distinguished collections of jewellery, predominantly from Parisian jewellers, such as Cartier. He reconstructed those items into a more modern styled collection and showcased his distinctive skills in design and in business. In 1932, Harry founded his jewellery store in New York. Some of the world's most renowned gemstones, including the 'Jonker', 'Vargas', 'Star of the East', 'Hope', 'Taylor-Burton', 'Winston Legacy' and 'Winston Blue' diamonds were owned by Harry Winston, hence his legendary nickname - the 'King of Diamonds' and 'Jeweller to the Stars'.
