Mosaic opals are very popular, as they display brilliant colour at only a fraction of what a solid-gem opal would cost.
A Mosaic Opal has three components: A thin slice of small pieces of crystal opals glued closely together, resutling in high visual impact; a black potch or manmade black resin backing to enhances the fire colour, and a quartz or glass top to protect the opal.
Mosaics make good ring stones, but it is recommended not to get them wet when washing dishes. We have seen many triplet rings over 20 years old that still look good and just need a polish on top, which a local jeweller can do.
Mosaic opals have stunning fire colours and patterns.
