What is Concave Faceting?

The Concave cut is three dimensional; where as the traditional flat faceted cut gemstones are two dimensional. The concave cut not only has facets in the length and width of the gemstone but also has conical shaped facets to create more depth. This third dimension further refracts the light as more ambient light, thus returning it to the eye as more brilliance in the gemstone. A two dimensional gemstone will need light to show its brilliance, a Concave cut gemstone will reflect the smallest amount of light. The gem will return to the eye, brilliance from even a small single candle that has been lit in a darkened room.

Beauty is in the eye of the beholder, some people prefer the traditional faceted design over the innovative Concave faceted gems. They like the more classic look of a traditional faceted gemstone.

Some of the disadvantages of Concave cutting are that darker gems like Ruby, tend too look less attractive when Concave cut, the gems turning out murky and less attractive. There is also a higher weight loss than in traditional faceting and Concave faceting requires more labor resulting in a much higher cost to the finished gemstone.
