The Vinci Diamond

Shlomo Cohen, creator of the 1982 Princess Cut diamond, has created a new cut known as the Vinci Diamond. Based on the "divine proportion," a golden ratio that was studied intensely by Leonardo da Vinci, who inspired the diamond's name, the diamond features a 62-facet pentacle cut. By contrast, a standard round-cut diamond has 57-facets. The perfect proportions of the diamond include three pentacle stars and give a stone with this cut unprecedented brilliance. The design is patented in Japan, Israel, Belgium, and the United States, and Cohen already has marketing plans in place.
