About Boulder Opal
*************************
*Fine specimens of boulder opal can exhibit all of the spectral colors through their distinct play of color.

* Boulder opal accounts for approximately 2% of all of Australia's opal, so it is quite rare. 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 phenomena, commonly mistaken for being one and the same.

* Boulder opal is often cut in irregular, free-form shapes, in attempt to maximise the size and value of the finished opal stone.

* Boulder opal is not typically treated in any way. They are naturally layered with host rock matrix. Boulder opal is often referred to as 'natural opal doublet', because of its shared similarities with opal doublet. However, opal doublet gems are assembled, whereas boulder opal is naturally layered with its host rock matrix.

'Opal' comes from the Greek word 'opallus', which loosely translates as 'changing color'.

Healing Properties

* Physically, it can ease pain and suffering associated with the abdomen, lower back and intestinal organs, including the liver, kidney and adrenal glands.
