Opal

Opale takes its name from the Sanskrit “Upala” which means gem or gemstone. This initial name would have given the Latin “Opalus” and the Greek “Opallios”, which mean “to see a change of color”.
Opal is a very special fine stone and, unlike other minerals, its crystals do not have a particular shape.
Lapidaries cut it into cabochon in order to preserve its play of lights. No two opals are the same, each opal is unique with its own fire.
