Gemstone French Back 5mm Solitaire Earring in 14K White Gold

4 5/8 Carat Cabochon Fire OpalThe name Opal was probably derived from Sanskrit "upala", meaning "valuable stone". This was the root for the Greek term "opallios", meaning "color change".
This "play of color" is one of opal's main characteristics. The gem is found in a range of hues, including white opal (the most common); black opal; "boulder" opal (black opal with iron oxide); crystal or water opal, which is transparent; and fire opal, which has a yellow to orange to red body color.
For this fantastic play of color are responsible small spheres from silica gel caused interference and refraction manifestations.
Opals with strong flashes of red fire are the most prized.
Most stones are cut and polished to round or oval cabochons to enhance color play.
Throughout history people have believed in the healing power of Opal. It is said to be able to solve depressions and to help its wearer find the true love. The color play of opal reflects changing emotions and moods of people.
With a hardness of 5.5 on the Mohs scale, opal is relatively fragile, and care should be taken not to scratch, chip or crack it.
