Yair Shimansky is a jeweler based in Cape Town, South Africa, specializing in diamonds. He owns several retail stores in South Africa,[1] and operates a diamond cutting and polishing business in Johannesburg, South Africa.[1][2] Shimansky is known for creating what is claimed to be the world's most expensive temporary tattoo[3] and a 900-carat diamond-encrusted soccer ball for the FIFA World Cup.[4][5][6]
The Brilliant 10 diamond design is a 71-facet round brilliant cut diamond design developed and patented by Shimansky.[7][8][9] After years of research and refinement, Shimansky created this 71-faceted round brilliant cut diamond featuring 10 arrows on the top and 10 hearts on the bottom. This design is claimed to be 25% brighter than other round brilliant cut diamonds.[10]
It's been stated as being the most brilliant diamond in the world.[7][11] The diamond is currently the only diamond that has no light leakage,[7][11] in which all of the light that enters through the table and the crown is reflected back. In contrast, a regular round brilliant diamond with 57 facets loses around 8%-12% of light even if cut to ideal proportions, in which the light loss is around the girdle area of the diamond.
