Description

A great specimen of rare botryoidal chromium chalcedony known as 'Mtorolite' named after its source in Zimbabwe. In terms of colour this is a top specimen from the locality. Nice form on one side with intense colour on the reverse. I have sold a number of these over the past year but this specimen has by far the best botryoidal form I have seen.
