Over 50 Gold and Gold-bearing specimens from Colorado !!
Gold is a word that needs no explanation. Crystallized specimens of Gold are some of my favorite minerals in the world. Several generations of my family has mined for Gold all over Colorado! Gold played a key role in the establishment of the state of Colorado dating back to the 1850's. We have assembled over 50 pieces of Gold and Gold-bearing minerals from all over Colorado in this update with some old historic specimens and contemporary pieces alike. Most specimens are very affordable, so be sure to check them out. With the growing popularity of Gold, pieces like this are even more than collector specimens. Please click here to view this update.

PREHNITE finger casts after Anhydrite from the Prospect Park Quarry, New Jersey
The Prospect Park Quarry is well known for its zeolites and associated species, including some of the best Prehnites from any locality in New Jersey (and arguably the world). During the latter half of 2010, one of the most significant discoveries in the history of this locality was made. Some of the finest quality cats (epimorphs) of Prehnite repalcing Anhydrite were discovered during this time, and we are proud to provide 2 pages worth of specimens for your consideration. Please click here if you wish to view these specimens.

ANDRADITE (Demantoid) from the Sferlun Asbestos Quarry, Italy
When it comes to Alpine Garnets, the Italian specimens are among the best in the world! Whether it be Grossulars or Andradites, the Italian specimens have set the standard for the Alpine material. The Demantoids from the famous Val Malenco (Malenco Valley) are among the most well-known and highly sought after Garnets in the world. I recently acquired a small parcel of specimens from the famous locality at Sferlun which were collected approximately 30 years ago (late 1970s to early 1980s), and remained in a private collection for decades. I am told that these pieces originally came through the Magistretti collection in Italy. Please click here if you wish to view these specimens.
