Sam Kwiat founded his company Samuel Kwiat Jewelers in 1907 on Canal Street in New York City. By 1933 Samuel's son, David, joined the business. David, together with his father pushed forward cutting diamonds which is where he focused his time. By the 1950's Kwiats business grew and other retailers began to source their diamonds from kwiat for their makes. Harry Winston, Tiffany, and others came to Kwiat for well cut stones for production. By 1962 Kwiat moved their location from Canal to to the newly up and coming "diamond" district on 47th street. The business grew and in 1965 David purchased a 126 carat rough which sold to Harry Winston. David cut the stone for Winston at the time which became known as the Teardrop of Africa. In 1966 Sheldon, David's son joined the company followed by Lowell in 1973. The business grows and changes direction between 1973 and the 2000's including a new focus towards the retail side of the jewelry business. In 2008 Kwiat opens their first flagship shop on Madison avenue in New York City.
