C-244  Calcite with Hematite  $120  $65
Ex. A. Rosenzweig collection

Santa Eulalia District, Municipio de Aquiles Serdán, Chihuahua, Mexico

7.5 x 4.6 x 4.7 cm

This is a type of Calcite that came out a long, long time ago from Santa Eulalia and has been unavailable - until a recent find in 2007. These Calcites are instantly recognizable by their strange form: an earlier generation of dark, opaque, hematite-included scalenohedral crystals seeming to emerge from within a later generation of translucent crystals of a lighter color.  This specimen is undamaged and is from the original find.

F-184  Fluorite with Calcite, Quartz and Pyrite  $350  $200

El Hammam Mine, Khémisset Province, Rabat-Salé-Kénitra Region, Morocco

15.5 x 14.5 x 4.1 cm

This specimen features many medium to dark-green crystals of Fluorite.  This specimen has several interesting features; the first being numerous water-clear Quartz crystals up to 3 mm. in size that cover the entire specimen.  The top of the specimen is blanketed with Calcite and there are dozens of brass-colored, ball-like Pyrites covering the specimen.  This Fluorite specimen is complete, with no damage.  The back of the specimen is flat , but shows many growth hillocks as well as many white, needle-like inclusions.  A good example of a combo specimen for this location.

C-277  Calcite  $1,200  $750
Ex W. Larson Collection
Ex R. Rizzo Collection

Hilton Deposit, Borrego Springs, San Diego County, CA

29 x 17.3 x 11.5 cm

A dramatic and huge plate of large Calcite crystals of from south-eastern San Diego County.  This impressive specimen features translucent-transparent, bladed crystals of Calcite measuring up to 10 centimeters in size. The Calcite crystals fluoresce a light-hued red\pink color. Known by locals as "The Calcite Mine" this location was operated from 1942 to 1944 for the Polaroid Corporation to produce optic grade Calcite in order to make the Polaroid Optical Ring Gun-sight. This specimen was a part of my award winning mineral collection and was judged best specimen from San Diego County and won the prestigious Josephine Scripps award in the mineral competition at the San Diego County Fair where there is some serious competition from local "heavy-weight" type mineral collectors. This location has been off-limits to collectors since 1974 when the area surrounding it was designated Anza-Borrego Desert State Park.
