Overview
Harry Winston is an American luxury jewelry and watch house founded in New York City by jeweler Harry Winston. The brand grew from Winston's expertise in sourcing, cutting, recutting, and presenting important gemstones, especially diamonds. He became widely known as the “King of Diamonds,” a description reflecting both his commercial prominence and his role in bringing historically significant stones to a broad public audience. The business has roots in the jewelry shop operated by Winston's father, Jacob Weinstein, a Jewish immigrant from the Russian Empire. Harry Winston worked in that environment while growing up and developed an early talent for recognizing gemstone value. As a young man he changed his surname from Weinstein to Winston. He began operating his own business in 1920 and opened his first New York store in 1932. A major early turning point came in 1926, when Winston acquired the jewelry collection of Arabella Huntington, widow of railroad magnate Henry E. Huntington. The collection contained pieces associated with leading European jewelry houses, but many designs were considered dated. Winston redesigned and remounted the jewels, demonstrating the technical and creative approach that became central to his reputation: important stones could be liberated from old settings and given new life through contemporary design. Winston's public profile expanded through his dealings in celebrated diamonds. Among the stones associated with him were the Hope Diamond, the Jonker, the Blue Heart, the Portuguese Diamond, the Idol's Eye, and the Lesotho diamonds. His most important philanthropic act was the donation of the Hope Diamond to the Smithsonian Institution in 1958. In 1963 he transferred the Portuguese Diamond to the Smithsonian in exchange for a parcel of smaller diamonds. These actions helped establish the house as part of the cultural history of gemstones rather than merely a retailer of luxury goods. The company also developed a close relationship with Hollywood. Beginning in 1944, Winston pioneered the practice of lending jewelry to actresses for the Academy Awards and other public appearances. The practice helped make high jewelry part of celebrity fashion and red-carpet culture. Harry Winston jewels subsequently appeared on major performers and in films including Alfred Hitchcock's Notorious, The Graduate, and Everyone Says I Love You. A reference to Winston in the 1953 musical film Gentlemen Prefer Blondes further reinforced his recognition outside the jewelry trade. After Harry Winston died in 1978, ownership passed to his sons Ronald and Bruce, whose disagreement over control led to a prolonged family dispute. In 2000, Ronald Winston and investment partner Fenway Partners acquired Bruce Winston's interest for a reported $54.1 million. The company was acquired by Switzerland's Swatch Group in 2013 for $1 billion, bringing the jewelry house into a global luxury group that also operates major watch brands. Harry Winston remains positioned at the high-jewelry end of the luxury market. Its business includes diamond and gemstone jewelry, bridal jewelry, watches, salon retail, and related client services. The house's identity continues to rest on exceptional stones, highly finished settings, New York origins, private-client relationships, and visibility at important cultural and entertainment events. In 2015, the company was reported to operate 39 salons alongside retail affiliates in the United States and other international markets.
History
Harry Winston's history began in the United States within the jewelry trade established by his father, Jacob Weinstein, who had immigrated from the Russian Empire. Harry worked in the family shop and developed an unusually strong ability to identify valuable stones. A frequently cited early episode describes him recognizing a two-carat emerald in a pawn shop at age twelve, purchasing it for 25 cents, and selling it shortly afterward for $800. He later changed his surname from Weinstein to Winston and entered business independently in 1920. Winston's reputation accelerated through the acquisition and transformation of important private jewelry collections. In 1926 he purchased the collection of Arabella Huntington, a prominent American collector whose jewels had been made largely by elite Parisian houses. Rather than preserving the pieces unchanged, Winston redesigned many of them, improving their relevance to contemporary tastes while retaining their important stones. This combination of gem acquisition, technical reconstruction, and modern presentation became a defining feature of his work. He established his first New York store in 1932 and built a business around rare diamonds and high jewelry. Winston was involved with a long list of notable stones, including the Hope Diamond, the Jonker, the Blue Heart, the Portuguese Diamond, the Idol's Eye, the Lesotho diamonds, and the Anastasia. He was known not only for buying and selling gems but also for making decisions about recutting, mounting, exhibition, and public storytelling. His treatment of major stones helped turn individual diamonds into recognizable cultural objects. Philanthropy became a major part of the firm's public legacy. Winston donated the Hope Diamond to the Smithsonian Institution in 1958, sending it to the museum by registered mail. In 1963 he exchanged the Portuguese Diamond for 3,800 carats of smaller diamonds, which also went to the Smithsonian. These donations strengthened the association between Harry Winston and public education about gemstones. The house also helped establish the modern relationship between high jewelry and entertainment publicity. In 1944 Winston began lending jewelry to actresses for the Academy Awards and similar events. This practice gave designers and jewelry houses a highly visible role in celebrity presentation and red-carpet fashion. Winston jewels appeared on performers including Jennifer Jones and Katharine Hepburn, and were used in films such as Notorious, The Graduate, and Everyone Says I Love You. Popular culture references, including the line in Gentlemen Prefer Blondes, made the name familiar beyond the specialist jewelry market. When Harry Winston died in 1978, the company passed to his sons Ronald and Bruce. Their conflict over management and ownership continued for approximately a decade. In 2000 Ronald, together with Fenway Partners, bought Bruce's interest for a reported $54.1 million. The company later expanded its salon network and international presence. In March 2013 the Swatch Group acquired Harry Winston, Inc. for $1 billion. Under Swatch Group ownership, Harry Winston operates as a specialist high-jewelry house within a larger international luxury group. The brand's contemporary identity continues to combine exceptional diamonds, fine jewelry, watches, private-client service, and the legacy of its founder's gemological and design expertise.
