Opal for Auction - Ross's Auctioneers & Valuers
Opal In scientific terms opal is a type of hydrated silica that is semi-transparent. There are many different types of opals available with a large number of colours; the four main types are black, crystal, boulder and white. The value of an opal is determined by a wide range of factors, however, perhaps the most important are the fire of the opal, visible colours, size and pattern.

Today the vast majority of opals are from Australia, however, opals are also sourced from Mexico, Brazil and Nevada. Opals are quite soft and are more suited to occasion pieces of jewellery.
