The precious opal has a unique internal structure. It is made up of spheres that
are closely packed in layers that eventually form something that looks like a
four-sided triangle or a hexagon. They are made up of silica that allows light
to pass through the structure like a prism to produce internal colors, and it
also determines the quality of the stone. A precious opal has a doublet which is
a colorful material laid on a black backing of ironstone, basalt or obsidian.
This causes "a play of color" which produces a spectrum of different colors.
