APZ1 Quartz var. Amethyst
Piedra Parada, near Las Vigas, Veracruz, Mexico
15.0x 10.9x 6.6 cm
$490

A cabinet sized cluster of purple amethyst points on matrix, from recent finds near Las Vigas.









APZ10 Vesuvianite
Jeffrey Mine, Asbestos, Quebec, Canada
4.4x 3.0x 2.0 cm
$0

A cluster of gemmy yellow vesuvianite crystals, from the now-closed Jeffrey Mine, also known for its stunning grossular garnets.







APZ13 Datolite
Bor Pit, Dal'Negorsk, Primorskiy Kray, Russia
9.5x 8.1x 1.6 cm
$0

An unusual datolite specimen for Dal'negorsk-- it is yellow.  The bulk of the datolites from the various localities in the area are greenish, but this one is very solidly yellow.  

 

The only other locality I can think of for obviously yellow datolite is Michigan's upper peninsula, but those are cryptocrystaline nodules colored by impurities, rather than being composed of actual yellow crystals.

 

The black crystals are very small ilvaites scattered over the datolite.  Slightly older material, with crystals on both sides.








APZ14 Pyrrhotite
Dal'Negorsk, Primorskiy Kray, Russia
10.1x 7.1x 3.0 cm
$385

A very large and sharp crystal of pyrrhotite from Dal'Negorsk.  The crystal displays textbook form and is remarkably well exposed-- usually they are half embedded in matrix.

 

There is a sizable chip on the upper right of the specimen (this is visible in the lower two images) but this is almost invisible when the specimen is displayed as shown in the image to the right of this description  








APZ15 Pyrrhotite
Dal'Negorsk, Primorskiy Kray, Russia
5.4x 4.5x 4.8 cm
$165

A group of brassy pyrrhotite crystals on a matrix of quartz and sulfides.







APZ16 Pyrrhotite
Dal'Negorsk, Primorskiy Kray, Russia
6.0x 5.4x 5.3 cm
$175

A group of lustrous, brass colored pyrrhotite crystals stacked on a matrix of quartz and sulfides, with a little bit of calcite.









APZ18 Dioptase
Mindouli Dist., Republic of Congo
3.0x 2.1x 1.0 cm
$200

A nice "toenail" of large and terminated dioptase crystals from a recent find in the Mindouli District in the Republic of Congo.  The bulk of the specimens were plates of rather jumbled crystals, but this one showed a bit more distinctness between its crystals.







APZ19 Orthoclase
Hirukawa Area, Nakatsugawa City, Gifu Prefecture, Chubu Region, Honshu Island, Japan
5.7x 2.0x 1.4 cm
$165

A sharp orthoclase crystal, from Japan.  Old material, collected at least 20 years ago. 







APZ2 Quartz var. Amethyst
Piedra Parada, near Las Vigas, Veracruz, Mexico
8.1x 7.0x 5.6 cm
$385

A cluster of purple amethyst points on matrix, from recent finds near Las Vigas.

 

Although this is a contemporary piece, the size and color of the crystals are more reminiscent of the specimens recovered here in the 1980's.  The bulk of specimens from this location typically consist of narrower crystals with the color concentrated near the tips (see the preceding specimen)










APZ20 Orthoclase
Hirukawa Area, Nakatsugawa City, Gifu Prefecture, Chubu Region, Honshu Island, Japan
7.8x 1.8x 2.2 cm
$175

A sharp orthoclase crystal, from Japan.  Old material, collected at least 20 years ago. 







APZ21 Axinite-(Fe)
Puiva Mount, Saranpaul, Prepolar Ural, Tyumenskaya Oblast', Urals Region, Russia
7.5x 5.5x 2.7 cm
$375

A decently sized cluster of brown axinite blades, with a slight purplish hue, likely from finds in the mid 90's. 







APZ22 Quartz incl. Cookite and Tremolite
Obira mine, Ono-gun, Oita prefecture, Kyushu Region, Japan
6.5x 2.7x 1.6 cm
$165

A quartz crystal included by hairy (tremolite?) and a couple cookeite spheres.  

A beautiful and unusual example of rare and unusual Japanese material. 








APZ23 Quartz incl. Cookite and Tremolite
Obira mine, Ono-gun, Oita prefecture, Kyushu Region, Japan
5.2x 1.8x 1.3 cm
$155

A sharply terminated quartz crystal included by hairy (tremolite?).

A beautiful and unusual example of rare and unusual Japanese material. 








APZ25 Anatase
Kharran, Baluchistan, Pakistan
4.5x 6.2x 2.8 cm
$250

A group of doubly terminated anatase crystals to 1 cm, on matrix, from Kharran.  

 

This piece comes from an Australian collection.

 

I have handled hundreds of these things, and this is one of the few where I can actually see a bit of geminess in the crystals-- the color is dark, but there are distinct zones or translucency.  That is particularly unusual in crystals of this size-- the few examples I had seen in the past derived their translucency from the thin geometry of the crystals








APZ4 Quartz var. Amethyst
Piedra Parada, near Las Vigas, Veracruz, Mexico
7.1x 2.6x 4.2 cm
$185

A doubly terminated, purple amethyst crystal with a sceptered appearance, on matrix, from recent finds near Las Vigas. 

 

Although this is a contemporary piece, the size and color of the crystal is more reminiscent of the specimens recovered there in the 1980's.  The bulk of contemporary specimens from this location typically consist of narrower crystals with the color concentrated near the tips.

 

The matrix has a light green hue that contrasts well with the amethyst, though which unfortunately does not show up too well in the photographs.








APZ5 Quartz var. Amethyst
Piedra Parada, near Las Vigas, Veracruz, Mexico
5.8x 3.7x 3.0 cm
$185

A terminated, purple amethyst crystal on matrix, from recent finds near Las Vigas. 

 

Although this is a contemporary piece, the size and color of the crystal is more reminiscent of the specimens recovered there in the 1980's.  The bulk of contemporary specimens from this location typically consist of narrower crystals with the color concentrated near the tips.
