DEC-1: Phenakite: Aquatero Claim, Mount Antero, Chaffee County, Colorado USA: $300.00

A cluster of lustrous amber-yellow Phenakite crystals to 1.5 cm. from Mount Antero, Chaffee County, Colorado USA. A great Antero phenakite with top luster and nice color. The crystals form an aesthetic grouping on part of a quartz crystal. Fits just barely in a thumbnail box, which could easily be removed, but as is makes a killer thumbnail. Better in person. Classic!

DEC-2: Aurichalcite: Kelly Mine, Magdalena, Socorro County, New Mexico: $100.00

Sharp, lustrous orange Wulfenite crystals to 1.2 cm. on calcite matrix from Los Lamentos, Chihuahua state, Mexico. One crystal has some very minor rubbing on one face but otherwise in great condition. Great aesthetics and lustrous, isolated crystals make this a very nice Los Lamentos wulfenite for the price in my opinion.

Pegmatites on St. Peter’s Dome are genetically-related to the Mount Rosa granite, a locally metasomatised subsolvus alkali granite belonging to a late-stage sodic pluton group within the Pikes Peak Batholith. St. Peter’s Dome Astrophyllite has been analyzed to be unusually rich in Rb, Nb, Pb and Zn (Pilonen et al. 2003,Canadian Mineralogist).

DEC-16: Fluorite: Coalcleaugh Mine, West Allendale, Northumberland, England, U.K: $750.00
Fluorite crystals are up to 6.5 cm. on edge 
form a large mound of intergrown cubes with good crystals on all sides. A few crystals have nicks to corners as expected for such a large piece that is also 100+ years old, but overall I think this is very minor considering the size and rare locality. Specimens like this are unobtainable today and this is a great addition to a serious collection of fluorite or British minerals at what I think is a reasonable price. This piece originally comes from an institutional collection and was probably collected 100+ years ago. I will work with you to find the most reasonable shipping option for this specimen, depending on your location, as it weighs ~19.5 lbs./8.4 kg.
