Liroconite is a very rare copper species found in the oxidized zones of just a few deposits, most notably here at the TYPE LOCALITY of Wheal Gorland. I am told that all good specimens we see today came out of the ground by the 1870s at the latest. This choice small cabinet has two nice pockets on the presentation side, the largest of which 2 cm across. The teal blue crystals in this pocket are highly lustrous and average about 3 mm in size. There are even areas of smaller, sparkly crystals on the back. Specimens of this size and richness are very scarce on the market. They only come up in old collections, and even then it is far and few between. Frankly, I buy every good one I can lay hands on for their beauty, uniqueness, and importance as historic pieces. The richness and quality of these crystals is quite high, the color is very saturated, and this piece has GREAT provenance (going back through several collectors to an old Schortmann's sale) and mineralogical significance.
