Product Description:

Concave cutting involves cutting facets that are three dimensional (curved). The technology to cut concave facets was developed by the American inventor Douglas Hoffman around 1990. It allows conical-shaped, three dimensional facets to be cut, so that each facet has depth as well as length and breadth. The result is that more of the ambient light is refracted and returned to the eye in the form of brilliance.

In order to find the concave-cut gems that you require, filter the results further by using the left-hand menu. You can buy concave-cut gems by gem type, color and shape. By using the top menu, you can search by carat weight, size, price, origin and other factors, to enable you to find the exact concave-cut gems that you are looking for. All items are in stock and ready to be shipped.

I had a great time searching all the lovely stones. This is my first precious loose stone purchase for my own work. I chose sapphire, and found some lovely briolettes. I wanted 3, but this set of 4 was perfect. Everything was quick and easy, and I'm excited.

I love your selection of gems. My only complaing is I wish I could put in a page number to return to that page.When there are over 60 pages of gems it is hard to return to a page with a gem I am considering.
