On Fire Opal
Gemologists love to study the stone's structure as it is actually a mineraloid; it's amazing crystal system is amorphous. Under high powered magnification, micro-spheres appear which accounts for some opal's refraction of light and aura borealis-like color play.
As jewelry fans have more access to stones from distance locales, new favorites emerge. Opal lovers are increasingly fond of Fire Opal which mostly comes from deposits in Mexico.
This fiery chili-pepper hued stone makes for exciting jewelry like award winning designer Yael's Fire Opal and diamond ring shown here. The smoldering stone seems to be lovingly restrained by delicate strands of diamond. This ingenious pairing of icy cool diamonds and the torrid toned opal is an unexpected treat; obviously the designer found a muse in opal.
