    Default Opalized Pearls!

    A pity they are so tiny. Now, another castle in the air: to find a large opalized pearl and win the lottery.

    Since they are from Cooper Pedy, I would imagine they once were salt water.

    About 25 or 30 years ago, Greg and I travelled to North Carolina and there was a shop selling the most gorgeous rocks. Labradorite, amethyst geodes, etc. etc.

    In the window, there was an opalized ammonite about 1 FOOT in diameter. It was not for sale. It was gorgeous. Almost pure opal with just a little bit of matrix. Priceless, I'm sure.

    Oooooh! That must have been amazing. A small opalized clam is on my wish list. A nice one is doable.

    I once saw a couple of opalized pine cones. So cool!

    Drool. I'd like an opalized clam, too. Can't afford anything else this year, so I will just have to enjoy photos.

    Real opal gems are hydrated silicium oxyd, not aragonite as pearls, but theirs special look is probably made by a internal building similar at this kind of gem. So, opalescent pearls might be sensible to humidity, needing it, so much than real opal gems.

    These are, in fact, real opals. They are 65 million year old pearls that went a fossilization process, where silica dissolved in the water replaces calcite and aragonite. Coober Pedy produces plenty of opalized bones, crustaceans and other cool stuff. This, however, was the first time opalized pearls were found. After all, we are talking about the chances of a natural pearls occurring, it getting opalized, getting found and someone thinking it looked odd enough to warrant some investigation. Slim picking indeed!

    Ok Lady_Disdain, thank you for your explain ! Theorically, it's not absolutly impossible to find somes contemporary natural opalized pearls (it's an optical effect that many material can do, glass etc...), but if fossilized, this physical phenomen is not unusual. However, such a opal quality from fossilization is rare, opal is more often a ordinary stone, without special lightning, as fossilized pieces of wood.

    BPD - thanks for bumping this thread..I'd missed it before. Amazing find - if you look at photos of the Coober Pedy area it's remarkable that they found these little guys.
