Famous Diamonds in the World The Blue Lili Diamond
The Blue Lili Diamond
Origin of name
The Blue Lili diamond finds its name from the wife of William Goldberg, the former President of the famous William Goldberg Diamond Corporation of New York City, a company established in 1973 that focuses on the cutting, sparkling and sales of high-end large diamonds, fancy colored diamonds and diamond jewelry.
Characteristics of the stone
The Blue Lili diamond is a cushion-cut blue diamond of mysterious color and clarity grade, weighing 30.06 carats.
As all new naturally colored blue diamonds, the Blue Lili diamond is as well a Type IIb diamond, in which the blue color is originated by the existence of sketch quantities of boron in the crystal structure of the diamond. These diamonds are nitrogen-free and then classified as Type II, as different to Type I diamonds that include nitrogen impurities. It is essential to note that both boron and nitrogen have atomic sizes similar to that of carbon, the element that comprises the diamond crystal and as such can be simply lodged in the crystal structure. The presence of boron atoms in the crystal modifies the combination spectrum of the diamond creating the blue color.
History of the diamond
Nothing is known about the early record of the diamond, such as the country and pit of origin, the date of discovery, the load of the rough stone, etc. But, allowing for the color and size of the completed stone, certainly it must have initiated in the Premier diamond mines of South Africa, the only resource of blue diamonds of important size in the world today. The diamond must have been procured from De Beers by William Goldberg Diamond Corporation. The master cutters of the Goldberg Corporation had cut and refined the stone into the cushion-cut blue diamond of 30.06 carats, which was then named as the Blue Lili diamond.
