Boulder Opal is an absolutely magnificent gemstone. Arguably the rarest and most valuable of all Opal gems Boulder Opal is a diminishing resource (which means it is genuinely running out). Each Opal is unique, each gemstone is hand-carved from 'veins' of Opal colour that ebb and flow through the heart of the ironstone. If you are looking for a genuinely rare form of Opal that is incredibly unique, then Boulder Opal is the one! Technical Specifications Genuine Natural Australian Boulder Opal consists of a hydrated amorphous form of concretions of SiO2•nH2O silica consisting of spheres of silicon dioxide molecules arranged in regular, closely packed planes filling the cracks and crevices of Boulder Opal ironstone found remotely in Queensland Australia. Boulder Opal is a diminishing resource with anecdotal evidence suggesting increases in value of up to 15% per annum. Guaranteed free of dyes and artificial colour.
