R138 - Fluorite $ 800 (=~ CAN$ 1098) Yaogangxian Mine, Hunan, China small cabinet - 7 x 4.5 x 3 cm
Gem transparent Fluorite crystals without matrix. These are fine, undamaged blue/green cubic crystals with phantoms. The two main crystals are aligned side-by-side and the internal purple phantoms give the appearance of eyes. Photos don't do justice to the brightness and transparency of these crystals! You can see right through the crystals. From older finds.
R140 - Whewellite, Ankerite $ 650 (=~ CAN$ 892) Kladno, Central Bohemia, Czech Republic miniature - 5.0 x 4.5 x 4.5 cm
Uncommon matrix Whewellite from the Czech Republic. A breccia fragment sprinkled on all sides by white Ankerite crystals with a white, twin Whewellite crystal 1.5cm in size. Whewellite is a rare organic species that is seldom seen on matrix, especially with a crystal that stands upright on the matrix such as this one. Comes with a couple old collection labels.
R141 - Rhodochrosite with Stilbite, Sphalerite, Chalcopyrite $ 350 (=~ CAN$ 480) Davidkovo, Bulgaria small cabinet - 8.5 x 7 x 4.0 cm

Large single crystal of Microlite from Alto Ligonha. Translucent red with sharp edges, this is one of the better, larger crystals I've seen from the find. The label shows it as Fluorcalciomicrolite but I have also seen these sold as Oxystannomicrolite. Ex. Carl Acosta collection.

Fine thumbnail-sized specimen of Buergerite (FluorBuergerite). Numerous shiny, dark brown crystals to 9mm are scattered on the surface. Beugerite is a rare species in the Tourmaline group. This locality (the Type locality) produces the world's best specimens. Interestingly, this locality was once lost for many years and later rediscovered.
