GRAIN
This is a technique used to set the gemstones by dragging metal over them with a pointed burin, then shaping it with another one with a concave or rounded surface, producing a shiny effect around the stones.
PAVÉ
This is the same technique as grain setting, but with a number of gemstones grouped together.
CLAW
This is a technique where the gemstone is set held by metal claws shaped using a burin.
BEZEL
In this technique, the gemstone is set held by a metal frame that is modified to fit it.
