Why you don't see CUT opals in jewelry– Gemcutter prepares orange opal

How is a gem cut and polished? Today's gemstone that's ready for precision cutting ( aka: Faceting ) is something rarely seen commercially: Crystal Opal. Just as exciting: It's in a natural, fiery color! It's common to think of opal as opaque, and generally having a white complexion. But opal can actually be found in many colors—and can even be clear! "Crystal" (in this case meaning clear) is the preferred quality of opal for gemcutting, as it will allow light to enter inside. Today we'll perform the lapidary art of cutting and polishing this vibrant opal, and see how its clarity will turn this (commonly-opaque) gem into a brilliant gemstone.
