RAINBOW GEMS INTERNATIONAL, EDDY ELZAS
From 2014 Gems Expertise Larisa Popova was working with EDDY ELZAS, King of the coloured diamonds. On January 2020 Larisa Popova and Eddy Elzas opened their office together in Diamond Bourse, Antwerpen, Belgium.
Eddy Elzas is not only one of the world’s most uthoritative figures on the subject, he’s also the man who sparked the revival of natural fancy-coloured diamonds in the 20th century by daring to ask: “Who says diamonds should be white?” In town to unveil his fabled Rainbow Collection, the world’s largest and finest assortment of intense-coloured diamonds, the Antwerp diamond dealer talked about his prized possession. In 1981, Elzas was offered a ridiculous sum by a Saudi Royal, who wanted the whole collection as a wedding gift for Prince Charles and Princess Diana, but he turned down the offer. “There are 300 diamonds in the Rainbow Collection and each one of them is special,” he said. The stones have been exhibited more than 50 times at various locations around the world. The value of collection is more then USD$ 60 million. In the early ’80s, he received a certificate from the Gemological Institute of America (GIA) stating that of the 8,000 fancy-color diamonds it had graded, 6,000 had been submitted by Elzas. His expertise was sought by princes, sultans, maharajas and Hollywood stars.
