We returned to explore another lead mine next to the 1st one.

just a snippet ant calacited stones are not cave pearls, a cave pearl is a grain of sand that is covered in calacite and are completely round like a pearl and as a rule there is one in each pool and can be as big as a marble I have some in white and brown and can be in many colours depending on
what the water passes through eg copper iron etc.
