Marquise Genuine Opal Cabochon

Opal is the world's most popular phenomenal gemstone, with many cultures believing that Opals had supernatural origins and power. Inside of Opal are sub-microscopic spheres stacked in a grid-like pattern, similar to a layer of ping pong balls. When light hits theses spheres, the light waves bend and break into spectral colors. This produces a flash of rainbow colors or "Play of Color." White Opal is translucent to semi-translucent with play-of-color against a white background. Opal requires special care due to being extremely soft and can craze from loss of moisture. 

• Translucent white background with medium to strong play-of-color. Play-of-Color ranges from blue, green, and red.
• Treatment: None
• Opal is the birthstone for October
• NEVER clean with ultrasonic and steam cleaner
