Certified Gemstone



This is a slice of natural untreated rough silica specimens from Utah USA. They are also known as bacon opal due to its intersting strips of assorted colours-this is quite a collectors item.It takes a good polish.

Hydrated Silicon Dioxide (SiO2·nH2O)

Weight  57.80 cts app

Size   52 x 16 x 14 mm app

The quality varies quite a bit. Most is in layers of honey brown and
cream (hence bacon) but other hues occur including purple and red.
Almost none of it shows the mixed flash of precious opal, but it is an
interesting material nonetheless.
