Interesting Fact: Dioptase was named in 1797. Its name is derived from a combination of the Greek words Dia, which means " through" and Optasia, which means "to see". This is regarding the ability to see internal cleavage planes within transparent to translucent crystals of Dioptase.
A hydrous copper silicate, dioptase has been called "emerald copper" because of its color.
