The round brilliant is the most brilliant of all diamond cuts. Brilliant cuts were first developed by Marcel Tolkowsky (1899–1991) who came from a Belgian family of diamond cutters, and derived the cut from mathematical calculations that maximised the brilliance and dispersion of light.
Since its creation in the early twentieth century, the round brilliant cut has become the most researched and popular of all cuts. It is comprised of 58 facets and naturally follows the crystal shape of a rough diamond therefore designed to give maximum scintillation, beauty and fire.
The most beloved – and well-known – aspect of a diamond is inevitably its brilliance. Then there’s also sparkle and fire. These factors all work together to give a diamond their famous appearance. These terms should not be mistaken for one another, though, and cannot be used interchangeably to describe a diamond’s visual properties.
IN A NUT SHELL…
This is one of the more generally well-known terms used to discuss diamonds. Brilliance refers to the light that is reflected from the surface of a diamond. Because brilliance is the quantity – or, rather, the quality – of light that is emitted from the top of a diamond. Diamond cut has a large impact on brilliance.
When a diamond is rocked back and forth, colored flashes of light can be seen – this phenomenon is known as fire. Not surprisingly, diamonds with better cut grades will give off a greater variety of colors as they are tilted from side to side.
Scintillation is sparkle. Scintillation is the play of white and colored flashes of light seen when the diamond is viewed in motion. Seen with the naked eye, scintillation is the life of the diamond.
