Opāls (Opal, Опал )

Opal was formed many millions of years ago, when a combination of silica and water flowed into cracks and spaces in the ground. This then gradually hardened and solidified to become opal. Opals contain water, which makes them very sensitive to heat. They are soft and can be cracked or chipped easily. Opals should be stored in moist absorbent cotton.

Opal Care: Soak solid opal in plain water for about an hour once a month. Water is one of the chemical components in opal and can be gradually lost over time, causing the stone to crack (this is called crazing). Never put opal in oil or in detergent solution, because it may lose the color. Remove dirt by gently wiping with tissue paper moistened with rubbing alcohol. Opal should never be heated. [5]
