Boulder opal is one of the most valuable varieties of opal, second only to Australia's black opal. Fine specimens of boulder opal can exhibit all of the spectral colors through their distinct play of color. Boulder opal may is actually much rarer then black opal only accounting for 2% of Australia's Opals.
Boulder opal is found embedded in large boulders of ironstone, which is how it earned its name. Occurring as pebble rock, precious opal develops within thin veins, fissures and hollows. As opal miners attempt to remove the embedded opal from the ironstone, some of the host matrix is preserved during the process. For this reason, boulder opal is sometimes referred to as Opal in matrix. The ironstone matrix enhances the stones durability and vibrancy of color, often increasing the desirable effects of 'play of color' and 'opalescence', which are two different optical phenomenon, commonly mistaken for being one and the same. Boulder opal is similar to layered Opal Doublet, but rather than being assembled, boulder opal's layering is a natural occurrence.
