Aragonite "Cave Pearls" from Austria

Size: 7.4 x 9.1 x 3.0cm

Weight: 120g 

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 11 visible pearls with 8 loose and 3 fused onto the main structure.

This specimen comes with a custom display base.
