CLASSIC KONGSBERG SILVER!
This incredibly sculptural specimen features a gnarled 6 cm growth of Native Silver on Calcite and host rock matrix! I love the way the specimen was trimmed to leave most of the matrix but it could be trimmed further if so desired. With a little bit of addition trimming, this could become even more of a Silver specimen and it would probably increase the value even further. The Silver is beautifully patinaed with an original golden toning over lustrous surfaces. The knarled tree-like wires begin as thick 1.5 cm ropes near the base and twist upwards atop the Calcite matrix. Darker bits of Acanthite are visible here and there amongst the Calcite. A truly spectacular specimen! Locality: Kongsberg Silver Mining District, Svene, Flesberg, Buskerud, Norway. Measures: 7.7 cm by 5 cm by 5.7 cm in total size. Ex. E.C., Brown Mineral Collections Comes with a custom made, labeled display base

**VERY RARE!! Historic specimen featuring Acanthite crystals on Erythrite (Cobalt bloom) covered matrix! Specimens of this combination from Cobalt are so rare that you'd be lucky to see one in a decade. This is the first I've offered in the history of this website (15 years) and I've seen no others, not even during my visit to Cobalt several years ago. Simply put, not many large Acanthite specimens with their original Erythrite coating survive from the Cobalt Mining Disrict. Most were cleaned or had their Erythrite bloom removed and that is a shame because it's such a large part of the region's history. Erythrite, being a Cobalt mineral, is also the reason behind the town's name. This large plate has been preserved since it was mined in the early 1900's and the Acanthite crystals are lustrous, measuring to 1.5 cm in size. They are well scattered atop the red surfaces. This specimen is a rare opportunity to acquire an original specimen from a great Silver mining district. From the O'Brien Mine, Coleman Township, Cobalt area, Cobalt-Gowganda region, Timiskaming District, Ontario, Canada. Measures 12 cm by 13.5 cm by 3.4 cm in total size. Ex. Robert W. Hauck Mineral Collection Comes with a custom made, labeled display base Price $15,000

Gorgeous specimen featuring gem golden Calcite crystals with Quartz var. Amethyst! A wonderful combination piece which displays a cluster of golden Calcites with some of the sharpest, most distinct phantoms I've seen in a long time. A sparkling micro-crystalline coating of Hematite sprays outlines the earlier terminations which are now visible through the gemmy, glassy Calcite exteriors. This cluster sits alongside a gemmy purple cluster of Amethyst crystals which display some of their own internal phantoming. There are also two additional isolated Amethyst crystals atop the Calcites. In excellent condition. From Ametista do Sul, Alto Uruguai region, Rio Grande do Sul, Brazil. Measures 9 cm by 11 cm by 7.2 cm in total size.

Very rich specimen of greenish-brown Embolite crystals with Goethite and Cerussite! Chlorargyrite is the mineral known as "Horn Silver".

This specimen is covered with the waxy-brown crystals which are accented by iridescent (bluish-lavender) Goethite and tiny twinned Cerussites! I haven't seen this combination of minerals from the Broken Hill before and it's very nice. From the Broken Hill Proprietary Mine, Broken Hill, Yancowinna Co., New South Wales, Australia.
