#Karstmas day 22

I love cave pearls, they are one of my favourite formations. So when we found a bunch in a new cave we discovered, dug open, explored, and surveyed, I was quite excited!

Similar in a way to the pearls you may think of, they form often around a bit of sand or a teeny tiny rock, when the water hits it and precipitates out some calcite. They develop extremely slowly, and are a relatively rare formation due to the precise situations they require in order to form.
