Aragonite "Cave Pearls" from Austria

Size: 10.0 x 8.2 x 3.3cm

Weight: 132g

This unusual aragonite specimen from Austria is commonly referred to as Cave Pearls or sometimes Bird's Nest aragonite. These form in caves and mines where a thin layer of white aragonite covers the matrix material and there is a natural indentation where matter can collect. The "pearls" start with something small like a grain of sand and then accumulate aragonite to form these bean-like pebbles. Sometimes the pearls fuse to the floor, and sometimes they are all loose. In this specimen there are many visible pearls with 3 loose and the remaining fused onto the main structure.

This specimen comes with a custom base.
