About Jelly Opal
Formula:
SiO2 · nH2O
Name:
The origin of the word "opal" is uncertain. It may be from the Sanskrit "upala", meaning "stone" or "precious stone" or from opalus, the ancient Latin name for the gem (Pliny the Elder, 75-79). Pliny may have also referred to the gem as paederos, but a modern commentary by Kostov (2008) questions if that name was actually applied to the opal in the modern sense.
A transparent opal with a gelatinous appearance and a bluish sheen.
