  • This is an interesting piece! Sharp, lustrous titanite crystals almost totally cover magnetite crystals and, I expect, were derived from the magnetite which presumably titaniferous! A little bit of a magnetite crystal is exposed on one side. Lots of elongated fluorapatite crystal sections are embedded in the titanite and magnetite. Fine looking specimen of an unusual association.

This location was mined for electronic-grade quartz crystals during the second world war and they also came across these excellent calcite clusters, as well. Looks fantastic!

  • Silver
  • 9.3x5.0x6.1 cm
  • Largest Crystal Size: 2mm
  • $95.00
  • Sierra Nevada Mine
  • Zacatecas
    Mexico
  • This specimen is a fragment of a galena/carbonate vein. On a couple of sides there is a coating of crystallized silver that, in open spaces manifests itself as wires. They are small but there is lots of silver on it! The galena is relatively fine grained and embedded in the carbonate. There are also small pyrite crystals embedded in the carbonate. The label says "argentite" as well but I cannot see any. Could be! It is accompanied by an antique Harvard Mineralogical Museum label.
SpaleritePine Point Mine, Pine Point, Northwest Territories

The sphalerite is a very light brown colour on the outside indicating low iron crystallization while the inner cores shows darker brown indicating high amounts of iron earlier in the crystallization. This would be a "schalenblende" type of formation. Displays very well!

  • An interesting sawn and polished slice of silver and arsenic mineralization. It shows silver crystals at the core, over grown by inter-banded native arsenic and calcite, with calcite as the main vein gangue mineral. It is possible that some of the arsenic is stibarsen but I cannot be sure. Very nice specimen of this famous combination!

  • Iron Mountian
  • Beaver Co.
    Utah, USA
  • A wonderful plate of crystals that are, in fact, pseudomorphs of hematite after magnetite. The crystals are sharp and show the simple octahedral crystal form. As well, there is a younger generation of smaller crystals scattered about the large crystals. In addition, there are dark green, thick tabular crystals of a pyroxene group mineral, probably epidote, 7mm or so in size, scattered about. There is probably some relict magnetite in the specimen somewhere since it is slightly magnetic but nowhere near as magnetic as if it was fully magnetite. An old timer! Displays very well.

  • White Raven Mine
  • Ward
    Colorado, USA
  • This is an interesting one! It consists of barite crystals covering the top of it and all of the barite crystals are encrusted with quartz and a beiger/brown carbonate, probably siderite. On one side of the specimen there are many fairly sharp cube-octahedral of galena. On the bottom of the piece is a vug that has siderite, stephanite and small clusters of silver wires. There is an antique label affixed to the specimen that says the "barite" crystals are pseudos of quartz after baryte. I see none that are actually pseudomorphs. Great old time specimen! The label also has the specimen as from the collection of J.C. Cooper, Topeka, Kansas. Great old-time specimen!

    Ontario, Canada
  • A slice from a piece of a high grade vein from 1928. No oxidation or weathering because this piece was fresh from the operating mine way back then, not a modern day waste dump find. (Not that there is anything wrong with THEM, just sayin') Probably about 80% native silver by volume with the rest, mostly calcite with a relatively small amount of arsenide mineralization. The arsenide and carbonate mineralization appear to be brecciated in the silver and cemented by massive native silver and silver veinlets. Amazing high grade!

  • A slice from a piece of a high grade vein from 1928. No oxidation or weathering because this piece was fresh from the operating mine way back then, not a modern day waste dump find. (Not that there is anything wrong with THEM, just sayin') Probably about 70% native silver by volume with the rest, mostly calcite with a relatively small amount of arsenide mineralization. The arsenide and carbonate mineralization appear to be brecciated in the silver. Not cut quite straight;4mm thick at one end, 7.5mm thick at the other. Amazing high grade!

  • A really nice, elongated, lustrous hubnerite crystal nicely encrusted with white quartz crystals. The hubnerite crystal is dark brown but with deep red internal reflections sparking here and there. The hubnerite crystal is singly terminated and divergent so it has three separate terminations at the terminated end. A little damage to the terminations but sides of the crystal are pristeen. The hubnerite crystal is propped up by quartz crystals and in fact, the hubnerite crystal makes a great matrix for a wonderful quartz cluster!

There is also some carbonate which has been partly removed to reveal, sharp cube-octahedral of skutterudite. Where the aggregates are broken at the sides of the specimen, it appears that the skutterudite formed on nickeline. Of course, with these minerals, the specimen is dense! Very interesting specimen from an unusual location!

  • THIS is an interesting specimen! It shows two large, complex sphalerite crystals that are partially covered with 2-4mm, golden tetrahedral crystals of chalcopyrite. Of note, though, is that the chalcopyrite is oriented or epitactixially oriented on the sphalerite, so that the chalcopyrite crystals all flash at the same time because they are all oriented in the same way. I've tried to show this in one of the photos. The matrix is a thin plate of cherty limestone with the two large crystals on it and smaller sphalerite, chalcopyrite and dolomite crystals in between and around. Attractive and excellent specimen!
