RM2670   Opal with dendrites

Monto Outcrop, North Burnett Region, Queensland, Australia

Very bright opal from this Australian locality, with orange colors, the elongated dendrites of pyrolusite give it an aesthetic touch. This locality is formed by basaltic rocks over an area of more than 1000 km², most of them north and south of the Dawes mountain range. The main period of volcanic activity was at c. 25Ma. Acquired by Joan Astor from the well-known Jaume Serrate (Terrassa), whom we could describe as a "craftsman" of minerals.

RM2075   Dravite

Yinnietharra station, Yinnietharra, Upper Gascoyne Shire, Western Australia, Australia

Dravite crystals of Yinnietharra are a classic of the world mineralogy. Today, they can only be obtained from old collections that were fortunate enough to be formed when the mines were worked. This specimen shows us a group of doubly terminated dravite crystals, with very well defined faces and edges, bright and with the characteristic color of toasted honey. They are accompanied by muscovite.
Mining for muscovite used in the electrical industry occurred on Yinnietharra station at several sites between 1922 and 1946, beryl and columbite from 1942 to 1965, and gem specimen mining after this till around 1990. Minor rare earth, uranium bearing and lithium minerals are present but have never been mined to any extent. No mining on the field has been large scale.


Size: 5.8 x 4.6 x 4 cm.
Main crystal: 5.3 x 3.3 cm.

RM2077   Stichtite with serpentine

Tunnel Hill Quarry, Serpentine Hill, North Dundas, Zeehan district, Tasmania, Australia

Good sized specimen of stichite, very rich and aesthetic. It comes from the mining area in which the species has its Type Locality, in Tasmania. The brightness, the intense purple color, the waxy luster and the fibrous shape make it a quality piece. In a serpentinite matrix. A highly representative combination of this rare species. The stichtite is a rare hydrated carbonate of chromium and magnesium from the group of the hydrotalcite.

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.

RM1367   Ilmenite with epidote

Arkaroola Bore, North Flinders Ranges, South Australia, Australia

RM628   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 see a group of very defined crystals, one doubly terminated. Excellent transparency and smoky color zoning. On matrix. A very aesthetic and elegant piece.

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.
