Very rare Tarbuttite mineral specimens. The colouring of these stones is brown with patches of orange and white. This is a rare phosphate mineral and the specimens were mined at Kabwe Mine, Central Province, Zambia.
Please note that as these are entirely natural and have not been polished or smoothed in any way, it is normal that some loose material may become detached. These are very delicate stones.
