(Ca,Fe3+)2Cu5(Bi,Cu)(PO4)4(H2O,OH,Cl)13
Colour:
Dark brown
Lustre:
Resinous
Hardness:
2

Name:
For Reverend John I. Bleasdale (1822-1884) for his promotion of mineralogy in Victoria, Australia.
Bleasdale came to Melbourne in 1851 where he worked as a Roman Catholic priest. Furthermore, he was a founder of the Microscopical Society and active member of various other organisations, including the Royal Society. His obituary says: "As an authority on wine and precious stones, he was admittedly without a rival in the southern hemisphere."
