A fine old Cornish classic, a cast composed entirely of Apatite crystals have formed casts after Anhydites. The specimen is crystallized on all sides with just a few spots of contact. Lustrous and sparkling and very three dimensional, the shapes of the Anhydrite crystals are sharply preserved. The Apatite crystals are very sharp, glassy, translucent brown color in hexagons with flat pinacoids. Choice, Ex KP hammond collection, these were at one time called Francolite which is now discredited but is a varietal name still in use.

A very large specimen of lustrous Botallackite from Cornwall. In several habits but mostly accicular free standing crystals in several vugs. This could be trimmed to make several specimens if desired, but is fine as is to my eye. A Cornish classic copper specie, a paramorph of Atacamite and Clinoatacamite, this specimen seems to have a druse of Langite (not x-rayed) as well. Botllackites is quite rare and when from other localities are not nearly as attractive as these.

Gem clear crystal in fine condition from this classic Cornish location. The crystal includes a crude but distinct internal "helix" pattern which adds considerable interest. A fine small specimen with delicate pale blue color and glassy luster.
An old Cornish classic, this pseudomorph is a complete and sharp replacement of the original twinned Feldspar. No damage or missing areas, this is a perfect floater. Textbook form much like a crystal model. Sometimes called "pig's ears" these are not "beauty" type display minerals but they are distinctive and unique to these old finds. Not many turn up for sale, this one is the best and sharpest example we have seen available.
Olivenite- well xl'd
5.5 x 3 x 2.3 CM (cabinet)
A really good Cornish Olivenite with fine color and contrast to the matrix. There are several other Copper secondaries on the Quartz matrix that add nice color. The crystal druze is sizable and in excellent condition. Classic old material that displays well.
Bournonite - classic Cornish

Post Tucson 2015
A nicely crystallized cluster of cogswheel form Bournonite from the famed Herodsfoot Mine. An old specimen (pre 1950 but likely far older), the color is a dark "gunmetal" metallic black. The crystals have several habits and reach 1.6CM. There is damage on the edges and minor chipping but the central area of this is in good condition. Overall nice specimen of this delicate mineral from this old classic Cornish locale.
Sparkly bright red cuprites on matrix with some native copper in classic form from a Cornwall classic locality. A lot of Cuprite here, some in crystals reaching 5 mm. Some damge is found with 10x magnification but many of the crystals are perfect and have very good color.
