Tumbled Stones are about 3,0 - 3,8cm in size and mostly roundish in shape
In the VE (=packing unit) with 0.5 kg are about 18 - 22 Tumbled Stone Amazonite (also called green Feldspar) included.
Amazonite is used in analytical stone healing according to Michael Gienger to achieve a harmonious interaction of mind and intuition.
Very well suited as a pocket stone!
