RM1367   Ilmenite with epidote

Arkaroola Bore, North Flinders Ranges, South Australia, Australia

This specimen is really interesting not only for the quality of the crystal but the locality it comes from. Few specimens are represented in collections. This sample shows a brilliant metallic luster and sharp faces and edges. Located in a gully, this locality consists of outcropping hydrothermally-altered and weathered Wooltana volcanics containing veins and pockets of zeolites, calcite and crystallised ilmenite.


Size: 5.3 x 4.7 x 2.8 cm.
Main crystal: 27 x 20 x 8 mm.



 

RM1623   Scholzite

Reaphook Hill, Martins Well, South Flinders Ranges, Flinders Ranges, South Australia, Australia

Very rich scholzite specimen, an unusual phosphate of Ca and Zn, with elongated prismatic crystals, transparence and brilliance. It comes from a classic Australian locality for the species as is the Martins Well area, about 40 miles SE as such indicates this old label. A zinc and phosphorus-rich deposit in dispirited breccia. It is as mined for a few years for mineral specimens (mostly scholzite).


Size: 6.4 x 4.4 x 3.2 cm.
Main crystal: 10 x 1 mm.

RM1390   Axinite-(Fe) with calcite and quartz

Colebrook Hill Mine, Colebrook Hill, Rosebery, Tasmania, Australia

If something I like about the world of selling minerals is to find specimens lost in the nooks of old collections. This sample is a case of this. It is an Australian piece, of good size, formed by a druse of ferro-axinite crystals, not very big, but with an excellent color and transparency. They are accompanied by calcite and curious milky quartz. The specimen comes from a locality located NW of Queenstown, Tasmania, a big skarn that was worked by their sulfides: pyrite, pyrrhotite, arsenopyrite, chalcopyrite. Under the calcite ferro-axinite appeared... But a long time ago.

RM1718   Pyromorphite

Sylvester mine, Zeehan, West Coast, Tasmania, Australia

Rich group of intense green color pyromorphite crystals with color zoning. From a locality unusual in collections. With Joan Viñals label and analyzed.


Size: 9.5 x 4.5 x 4 cm.

Col. J.M. Manchion, Barcelona.
 

RM1207   Crocoite

Adelaide Mine, Dundas, Zeehan, Tasmania, Australia

Rich group of elongated prismatic crystals of crocoite with an intense orange to red color very characteristic for the species. Brilliant and partially covering the goethite and rocky matrix.


Size: 12.4 x 5.8 x 4.5 cm.
Main crystal: 18 x 3 mm.

 

RM629   Smoky quartz

Anderson's Gully (Anderson's Creek), Mooralla, Southern Grampians Shire, Victoria, Australia

Specimens of this Australian locality are uncommon in the maket, but their beauty makes them stand out from the smoky quartz samples. It is very curious how these specimens nodules are found into rhyolitic matrix geodes called "thundereggs"; this vugs are usually covered by small milky quartz crystals, some amethyst... They are in themselves a treasure of Nature. In this specimen we offer we see a parallel growth, probably scepter, crossed with some crystals, one doubly terminated. Excellent transparency and smoky color zoning. On a small matrix. A very aesthetic and elegant piece.


Size: 4,5 x 3,4 x 3,0 cm.
Main crystal: 4,2 x 2,7 cm.

Anderson's Gully (Anderson's Creek), Mooralla, Southern Grampians Shire, Victoria, Australia

Specimens of this Australian locality are uncommon in the maket, but their beauty makes them stand out from the smoky quartz samples. It is very curious how these specimens nodules are found into rhyolitic matrix geodes called "thundereggs"; this vugs are usually covered by small milky quartz crystals, some amethyst... They are in themselves a treasure of Nature. In this specimen we see a group of very defined crystals, one doubly terminated. Excellent transparency and smoky color zoning. On matrix. A very aesthetic and elegant piece.


Size: 4,8 x 4,8 x 3,5 cm.
Main crystal: 23 x 14 mm.

 

RM1859   Malachite after azurite and wulfenite

Whim Creek Copper Mine, Whim Creek, Roebourne Shire, Western Australia, Australia

Specimens from this Australian mine are unusual today. In this sample we have a group of azurite crystals pseudomorphized by malachite, preserving very well defined faces and edges. They are disposed on a goethite matrix partially coated with malachite, chrysocolla and small yellow rystals of wulfenite.


Size: 8.2 x 4.5 x 1.8 cm.
Main crystal: 18 x 17 mm.
Found in ±1985.
