Concave Cuts
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.

Size and Weight

Gems are always measured in Millimeter (mm)

Dimensions are given as;
length x width x depth,
except for round stones which are;
diameter x depth

Select gems by size, not by weight!
Gem varieties vary in density, so carat weight is not a good indication of size

Note: 1ct = 0.2g
