The Smale/Royal Society exhibit included the world's best liroconite
and the world's best clinoclase "ball" of dark green crystals on matrix, as well as superb specimens of chalcocite, langite, olivenite, cornwallite and bournonite.
I particularly enjoyed seeing a superb Russian blue topaz and a vibrant blue and very rare liroconite
that dates back about 200 years, the product of a Cornish tin and copper mine.
But the gallery is totally lacking in fine barite, bournonite, witherite and liroconite
, and even the Weardale fluorites left much to be desired.
Most notable would have to be his stunning liroconite
from Wheal Gorland.
Another of his most important pieces was a superb liroconite
crystal on matrix from Wheal Gorland, Gwennap, Cornwall.
