The very essence of diamonds is to bring joy into the lives of people” – William Goldberg

Celebrated jeweller William Goldberg (1925 – 2003) was born to a candy shop owner in New York. Perhaps it was destined that his parents sent him to learn diamond cutting. During his apprenticeship, he realized that his true talent was discovering and bringing out the beauty in a diamond. It was then that he started his career as a diamond dealer. 
Over the ensuing decades, his name would become synonymous with the most spectacular diamonds in the world. Apart from the 136.25-carat Queen of Holland diamond, which was purchased by the company in 1975, some of the most legendary diamonds in history also come from William Goldberg. They include the Premier Rose, a 137.02-carat D colour Flawless pear-shaped diamond, the Blue Lili, a 30.06-carat trapezoid vivid blue diamond, the Beluga, a 102.23 carat D colour Flawless oval-cut diamond, and the Red Shield, a 5.11-carat Internally Flawless Fancy Red diamond – the largest Fancy Red natural colour diamond that the Gemological Institute of America (GIA) had graded up to that time. In 1999, William Goldberg introduced its unique, patented ASHOKA® cut diamond – an elongated antique cushion-cut with rounded corners and 62 facets. 
Throughout his life, Mr. Goldberg dedicated himself to diamonds and jewellery. He was elected President of the Diamond Dealers Club for three terms and received the Lifetime Achievement Award from Modern Jeweler magazine. The GIA inducted Mr. Goldberg into the League of Honor and the company’s celebrated coloured diamond collection was exhibited at the American Museum of Natural History. In 2005, the GIA named their New York Student Lounge in his honor. East 48th Street, in the heart of Manhattan’s diamond district, was also renamed William Goldberg Way in 2006, paying homage to Mr. Goldberg’s significant contributions to the jewellery industry.
