Description

Opal was formed many years ago, when a mixture of silica and water flowed into cracks and spaces within 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 may be cracked or chipped easily. Opals should be stored in moist cotton. We have finest quality of blue opal rough stone. At Lightning Ridge in Australia, they need a committee that values opal miner’s opals each Saturday. Several experienced opal values will price the opal per carat and thus the ultimate value is getting to be determined by the standard price per carat. The above factors can vary from person to person which is that the reason you'll see variation in price per carat amongst miners.
