The listing, Indian Marbles - Cave Pearls - cave marbles has ended.
6 Cave Pearls, also known as Indian marbles and cave marbles. They are about the same size as regular marbles, or slightly larger.
These are neither man-made nor marbles. They are naturally occurring geological formations found in caves, geological (stone) pearls. Most often they are spherical but not perfectly round - there are tiny bumps on the surface and occasional zig-zag line.
They form around a dirt nucleus (same principle as oyster pearls) by accretion of calcite / limestone in areas where water inside the cave flows too quickly for the formation of stalagmites.
Third photo shows a regular marble and a dime for size comparison. These two are not included LOL. Last 4 photos show the cave's natural environment.
