Q-552  Quartz pseudomorph after Gypsum (fluorescent) $50

Crawford Dam, Crawford, Dawes County, NE

9.5 x 8.7 x 7 cm

Nebraska is not necessarily the first state that one thinks of when it comes to mineral specimens, but these pseudomorphs from Crawford are some of the more noteworthy specimens from anywhere in the Cornhusker State. This piece is a group of what were originally Gypsum blades that were completely replaced by Quartz. Areas of the interior portion of this specimen exhibit yellowish fluorescence under LWUV light and other areas have bright green fluorescence under SWUV illumination which suggests that specimen is made up of both Chalcedony and Quartz. Fluorescence in Quartz is rarely observed.

Q-554  Smoky Quartz  $195
Ex Russ Rizzo Collection

North Moat Mountain, Bartlett, Carroll County, NH

20.1 x 8.5 x 6.2 cm

A very large crystal of Smoky Quartz from New Hampshire's most prolific Quartz location, Moat Mountain.

F-297  Fluorite  $60

Tongbai County, Nanyang, Henan, China

10 x 6.2 x 2.4 cm

This specimen consists of yellow Fluorite that has formed hundreds of blocky euhedral crystals on top of purple-colored Fluorite causing it to appear a deeper amber color. This specimen has has a good lustre with no damage, just contacting on the edges. These unusual Fluorite specimens caused quite a sensation in 2007 when they first appeared. Compared to the myriad of Fluorites that are available from China, there were very few of these to go around and they are much sought-after by collectors.

Q-549  Chalcedony pseudomorph after Aragonite  $65

Valle de las Plumas, Paso de Indios Department, Chubut Province, Argentina

9 x 7.6 x 7 cm

This group of Aragonite crystals have been pseudomorphed by Quartz, included by Hematite which gives it its reddish tone. So what you have is Quartz in the exact form of the prior Aragonite crystals, having preserved their form perfectly. There is some translucence at the terminations of the crystals. Once abundant, I don't see these for sale too often these days.

F-294  Orthoclase replacing Marialite (fluorescent)  SOLD

Pitwak Mine, Ladjuar Medam, Sar-e Sang, Koksha Valley, Badakhshan, Afghanistan

4 x 3.5 x 3 cm

A crystal of Marialite from several small finds made 7-8 years ago. The Marialite crystal is pseudomorphing to Orthoclase. The pseudomorph is not complete as Orthoclase has no fluorescence but the Marialite glows a rich yellow-orange under LWUV light.

F-295  Orthoclase replacing Marialite  $50

Pitwak Mine, Ladjuar Medam, Sar-e Sang, Koksha Valley, Badakhshan, Afghanistan

4 x 4 x 3 cm

A group of Marialite crystals from small finds made 7-8 years ago. The Marialite crystals are pseudomorphing to Orthoclase. This specimen seems to have almost completely altered to Orthoclase as very little fluorescence is observed. The blue color of these specimens is thought to be most likely due to minute Fe impurities that transition between Fe+2 and Fe+3.

F-296  Orthoclase replacing Marialite  SOLD

Pitwak Mine, Ladjuar Medam, Sar-e Sang, Koksha Valley, Badakhshan, Afghanistan

3.6 x 3 x 2 cm

A very sharp, well-defined A group of Marialite crystals from small finds made 7-8 years ago. The Marialite crystals are pseudomorphing to Orthoclase. The pseudomorph is not complete as Orthoclase has no fluorescence but the Marialite glows a rich yellow-orange under LWUV light; which can be observed on the rear of the specimen where is is contacted.. The blue color of these specimens is thought to be most likely due to minute Fe impurities that transition between Fe+2 and Fe+3.

G-164  Gonnardite replacing Haüyne (fluorescent)  SOLD

Sar-e-Sang River, Sar-e Sang, Koksha Valley, Badakhshan Province, Afghanistan

9.2 x 6.8 x 4.6 cm

A colorful and fluorescent mineral specimen from Afghanistan. The white patches are where the blue-colored Haüyne has been replaced by the zeolite mineral, Gonnardite. The Gonnardite fluoresces white, while the Haüyne strongly fluoresces a dark red. There are also several areas of the specimen that have amorphous Calcite that has an excellent vermillion-colored fluorescence. When these specimens first came out they were sold as Lazurite replacing Plagioclase. Closer examination and much testing has proven the blue mineral to be Haüyne. To be real Lazurite, it must be sulfide dominant and none have ever been found to be, so all "Lazurite" from this district is Haüyne.

F-298  Amazonite  SOLD

Klein Spitzkopje Granite Stock, Spitzkopje Area, Karibib, Erongo Region, Namibia

5.5 x 3.4 x 2.5 cm

A specimen of sharp Amazonite crystals from a classic African mineral locality. the crystals that make up this specimen have a good lustre. The blue coloration of Amazonite is due to the presence of lead as an impurity and the change from blue to white is due to the depletion of lead during crystallization.

F-299  Anorthoclase  SOLD

Pili Mine, Municipio Saucillo, Chihuahua, Mexico

7.5 x 5 x 4.3 cm

A good sized group of tabular Anorthite crystals whose faces show a bluish, pearly schiller effect. Feldspar from the Pili Mine has been variously labelled as Sanidine, Albite, Moonstone and Peristerite. The only published analysis of the Feldspar from this locality shows it to be Anorthoclase. Anorthoclase is a calcium-rich Feldspar. Specimens from this location are rarely seen for sale these days. Anorthoclase specimens from here were mined by Benny Fenn in the 1980's until he sold the mine. No work has been done since, largely because the claims lie within a major military reservation and surface access is tightly restricted.
