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 the matrix. The ironstone matrix enhances the durability and vibrancy of the stone of color, often increasing the desirable effects of 'play of color' and 'opalescence', which are two different optical phenomena, 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.
