Sterling Silver Imitation Opal Dreams Leverback Earrings

Opal, more than any other gemstone, is distinctly an individual. No other stone has as rich and varied a folklore. Precious opal displays rainbow-like hues that change with the angle of observation, especially in rounded cabochon forms. It was only in the 1960s that a team of Australian scientists analyzedOpals with an electron microscope and discovered the cause of opal's unique optical properties. It was discovered that small spheres from silica gel caused interference and refraction, which are responsible for the fantastic play of colors. The spheres, which are arranged in more or less compact structures, dissect the light on its passage through the stone.
