C-277  Calcite  $1200
Ex W. Larson 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 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 2014 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.

F-252  etched Fluorite  $65

William Wise Mine, Westmoreland, Cheshire County, NH

3.5 x 2.7 x 2.5 cm

The most famous Fluorites from any locality in New England are from the William Wise Mine.  Wise Mine Fluorites such as this one have a bright glowing green that is not matched in Fluorites from anywhere else. These specimens are well-known among collectors for their rich color and gemminess.  This piece has a rich green color with surface etching that makes for an attractive specimen.

Q-436  Calcite on Quartz with Sphalerite & Bitumen  $100

W.L. Davis-Deardorff Mine, Ozark-Mahoning Group, Cave-in-Rock, Hardin County, IL

11.5 x 5.5 x 3 cm

This specimen features many lustrous & glassy Quartz crystals which makes up much of this piece.  One side has a scattering of lustrous, black Sphalerite crystals and a patch of Bitumen.  The other side features numerous crystals of creamy-yellow Calcite.  Quartz is rare in the other nearby mines of the district.  This is classic, old-time material from this mine.  Open for only a short time in the mid-1900's the mine closed by the early 1960s. The Deardorff was considered to be THE specimen mine of this period in Southern Illinois.

Erongo Mountain, Karibib, Erongo Region, Namibia

6.9 x 5.7 x 4.1 cm

A translucent, color-zoned crystal of Fluorite measuring 3.5 cm accented by many smaller crystals on a little bit of corroded Microcline.  I consider these Fluorite specimens every bit as interesting and desirable as the Beryl and Tourmaline specimens from Erongo.

C-244  Calcite with Hematite  $100
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-183  Fluorite  $30

Judith Lynn Claim, Grant County, New Mexico

4.4 x 2.9 x 2.6 cm.

The octahedral Fluorite crystals from the Judith Lynn Claim have become very scarce over the years.  At one time it was not hard to find one for sale, but lately they're just not around anymore. This specimen has a nice purple-red color and has an interesting bumpy, fish-scale-like texture on the crystal faces.  These specimens, when you could still get them, were sold as being from Catron County to mislead potential claim-jumpers and poachers.

Q-146  Fluorite with Quartz  $65

Weardale, North Pennines, County Durham, England

10 x 9 x 4 cm.

This specimen features a pair of yellow and green Fluorite crystals, completely covered by hundreds of tiny Quartz crystals.  The dark spots on the side and top of the specimen are due to inclusions of sulfide minerals, accenting the 3-dimensionality of this specimen. This specimen, while relatively shallow in thickness, is not broken, but rather it is contacted on the bottom where it was attached to its matrix.  The numerous Fluorite mines in County Durham and the surrounding areas have long been renowned for their prolific production of minerals during the last several centuries.
