My first post here, I'm just after a trip into a cave in the beautiful Burren in County Clare where we found some amazing cave pearls that are covered in outward radiating calcite crystals. There are plenty of them occurring in a series of pools along a section of oxbow passage about 1m above stream level. The largest is about 3cm in diameter and they are not fixed in place.
Any other cave pearls I have seen are smooth on the outside - which I believe is the norm?
But a quick internet search showed up some photos of something that might be similar in Ogof Rhyd Sych in Wales.
So is this an unusual form of cave pearl?
Where else have they been seen?
How do they form a crystal coating but remain unattached?
