Gem Faceting Design Discoveries

Best/Ideal Round Brilliant Cut Diamond and Best Round Brilliant Cut Sapphire

Many discoveries await in this work written for the twin worlds of ‘Diamond Cutting’ and ‘Gemstone Faceting’. Discover the attributes and properties of the most beautiful round brilliant diamond cut, the Ideal Round Brilliant, and the reasons it possesses the best optical light performance.
Discover that those properties also result in the best beauty and light performance in other round brilliant cut gems as well. Chief among these discoveries is that the best small range of pavilion angles of the Ideal Cut diamond is universally the best for all round brilliant cut gems. This work explains and demonstrates why. Also revealed is the all-important connection between round brilliant design angles, and the gemstone’s illumination.
