Brilliant 10 diamond

The Brilliant 10 diamond is a 71 facet round brilliant cut diamond design developed and patented by Yair Shimansky in Cape Town, South Africa. It's been stated as being the most brilliant diamond in the world. The diamond is currently the only diamond that has no light leakage,<ref name="DiamondWorld"/><ref name="IsraeliDiamond"/> 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.
