Okay I know, it's only a small army.....3 hand-carved Magnesite caterpillars.
6cm long x 1.5 cm wide. (One army of 3 caterpillars)
Magnesite is a semi-precious gemstone ranging in colour from white to cream to green and into Chrysoprase. These three are all in the white range of the Magnesite. Magnesite is mined in Western Australia, but these are carved overseas.
