Opal is a mineraloid gel. It is made, oddly enough, almost entirely of opal.
It is also completely free of birefringence, and has virtually no pleochroism.
Opal is basically silica. Saying opal is made of opal is like saying quartz is made of quartz, or tiger eye is made of tiger eye. It's the unique structure of the silica that makes it become opal. The Japanese have made a nice man made opal using silica and zirconium oxide.
