Mysterious Opal - The October Birthstone, Gemstone!

The name Opal was derived from the Greek derivative "Opallios," meaning to see a change of color. Opal is a gemstone that ranges from semi-transparent to opaque. Its body color covers a broad spectrum of colors. This beautiful gemstone is mostly prized for what is known as "play of color," the ability to reflect and refract light into flashes of multiple colors. Thus, the phrase, "the fire of an Opal."

Choosing an Opal:

The brilliance or "fire" of the play of color is the most important value factor when choosing an Opal. After this consideration, the colors visible and their patterns will also influence value. Generally, opal with red fire is the most valued because the red will also reflect other colors when the gemstone is rolled back and forth. Generally large flashes and broad patterns are more rare and valuable than smaller patterns.

Opals range from 5.5 to 6.5 on the Mohs scale of hardness. It should be protected from heat, sudden temperature changes and strong light, which can dry it out, causing cracks. Ultrasonic cleaners, metal polish, acids, and any strong solvents should be avoided. Exposed corners or points on pear or marquise shape opals may chip if hit while they are being worn. Opal is best set in a protected mounting.

Lore and Legend of the Opal include beliefs that it heals the eyes and balances the metabolism. It was thought to aid inner beauty, faithfulness, and help recall of past lives. They were once considered the talisman for thieves and spies because it was thought the Opal's effect on sight could render the wearer invisible. According to one legend, opals were devils, half-serpent, half-human, who lurked in holes in the ground, luring men to their destruction with flashes of magic. In the Middle Ages, blonde women wore opal necklaces to protect their hair from losing its color.
