What is a Cabochon (Cab) Cut Gemstone
A cabochon (cab) cut gemstone has a
flat back and a domed top.
In this picture you will see a 16x12mm cabochon cut gemstone, otherwise known as a
cab cut gemstone with a 16x12mm cab setting. A cab cut gemstone has a flat back with
a dome top. The gemstone we have here is a tiger's eye cab cut gemstone. With
cabochon cut gemstone you would use a cab setting NOT a pre-notched or snap tite
setting. If you tried using a pre-notched or snap tite setting it would not work. This is
because the prongs of the settings do not have a deep enough notch in them to fully
wrap around a cabochon.
For cabochon cut gemstones you need to use Cab Settings. Snap Tite
and Pre-notched settings will not work for faceted cut gemstones
