Opal displays rainbow-like hues that have been prized for thousands of years . In the 1960s a team of Australian scientists analysed Opals with an electron microscope and discovered that small spheres of silica gel cause "interference and refraction manifestations". These spheres act on the light that passes through the gemstone and create the rainbow of colors that we see.
Almost ninety-five per cent of all fine opals come from the dry and remote outback deserts of Australia. Opals are often cut in cabochon, a rounded half-circle form, to best display their fire. The exceptions to this rule are the highly prized fire opals mined in Mexico, which have a warm, beautiful transparent red or golden color. Fire opals are sold in more traditional, faceted gemstone cuts and conventional settings.
Opals Love to be Worn
Opals always contain water – usually between 2 and 6 per cent, but sometimes even more. If stored too dry or exposed to heat over a period of time, Opals will show fissures and the play of colour will become paler. Therefore, Opal jewelry should be worn as often as possible, for then the gemstone will receive the needed humidity from the air and from the skin of its wearer.

This photo is a boulder opal a friend of mine brought back from Australia. I created a beaded bezel for it using peyote stitch and seed beads. The necklace is strung seed beads, Swarovski crystal and Czech glass beads. I love how the pattern on this side of the opal is reminiscent of a waterfall.
