Amethyst - Grape Chalcedony/Agate
stock #17.1-285
Manakarra, Mumuju area, Sulawesi Barat Province
Sulawesi Island, Indonesia
6.3 x 5.7 x 2.7 CM (cabinet)
price: $180
new year 2021

One of the most exciting and attractive finds of the past few years were these "Grape Agates" or Chalcedony spheres from Sulawesi. Now more correctly called botryoidal Amethyst, this material is unique in the mineral world and can be incredibly attractive. This is a select piece, well-formed on all sides with the desirable bicolor (green and purple) areas. The color on this piece is a good deep grape purple and the "front" is also covered with drusy Quartz that adds the most desired sparkling luster. In fine condition as seen, better specimens from this find are among the best values on the mineral market today, however recent mining has not been producing much of the higher quality.

Spangolite with Brochantite - classic USA
stock #19.1-920
Blanchard Mine, Bingham, Hansonburg District, Socorro County
New Mexico, United States
7.4 x 5.3 x 3.4 CM (cabinet)
price: $480
new year 2021

A very rich, sizable specimen of the uncommon Copper Sulfate Spangolite from the famed Blanchard Mine. The Spangolite is covering a quite large area with a few small zones of Brochantite crystals. The mineralized zone on this piece is much larger than the usual tiny patches. This piece has substantial areas of sparkling blue Spangolite with hundreds of tiny, gem clear crystals. The hard rock matrix gives a nice jagged contrast to the mineralized faces. Ex John Buckley collection, this is a far, far better than typical specimen from this classic and well-respected locality. This is one of the very few pieces that looks fine on a display shelf and also amazing under a microscope.

Fluorite with Calcite
stock #20.1-133
Orismuhle Quarry, Seltisberg, Liestal
Basel-Landschaft, Switzerland
7.3 x 3.8 x 3 CM (cabinet)
price: $320
new year 2021

Not often available for sale, especially outside of Europe, this is a choice specimen from the Orismuhle Quarry in Liestal, Switzerland. The Fluorites are sharp honey-yellow to orange cubes. The Fluorites are set among sharp scalenohedral Calcite crystals that add a good contrast. In good condition overall the largest cube is 1.3 CM across diagonally. The specimen is well trimmed section of a vug that has preserved most of crystals inside well. Excellent addition to a serious world Fluorite suite and certainly unlike most well-known Swiss Fluorites.

Beryl var. Aquamarine
stock #20.1-611
Erongo Mountain, Karibib
Erongo Region, Namibia
2.4 x 1. x 1 CM (thumbnail)
price: $70
new year 2021

Choice Aqua thumbnail with fine color from Erongo. A single mostly gem-clear Aquamarine crystal stands on a Microcline matrix with some small Schorl crystals as well. In excellent, undamaged condition, most of the Aquamarine is transparent with the top half having fine clarity. These Erongo Aquamarines are found every few years and are good value for quality to price.

Mixite - historic specimen
stock #AX-35-144
Mammoth Mine, Tintic Mountains, Juab County
Utah, United States
7.6 x 4.5 x 2.7 CM (cabinet)
price: $320
new year 2021

This specimen dates to the famed Levison collection (New York City) acquired in 1899. Mixite is considered fairly rare, an unusual Bismuth Copper Arsenate, almost never seen in display specimens. This is a sizable and complex multi-specie piece with a Barite matrix hosting areas of Mixite, Malachite plus what seems to be Olivenite. There are a few additional small crystals not identified. The Mammoth area of Tintic was a fantastic locality that provided some rare and exotic species including five new minerals. This specimen has a very tattered old label affixed (not easy to read) and we also include a photocopy of the page from his collection ledger for this piece. A nice example in a sizable specimen.

Smithsonite
stock #16.1-202
Tsumeb
Otjikoto Region, Namibia
2.5 x 1.8 x 1.3 CM (thumbnail)
price: $140
new year 2021

Sharp scalenohedral crystals of Smithsonite with a pale yellow color perched on a Sulphide matrix. Tsumeb Smithsonites were found in every color and form possible, this is a choice thumbnail in fine condition as seen.

Aquamarine - tapered termination, etched crystal
stock #AX-7-058-(162)
Medina Pegmatite field, Pedra Azul District
Minas Gerais, Brazil
5.1 x .5 x .4 CM (small cabinet/ large miniature)
price: $180
new year 2021

A "needle" of sharp gem-clear Beryl in perfect condition. The sides are etched along the "C" axis and the termination is the uncommon pointed, tapered type. Ex Larry White collection; this dates to the late 70's early 80's vintage.

Rhodochrosite
stock #20.1-606
Idaho Springs, Clear Creek County
Colorado, United States
1.4 x 1.2 x .8 CM (thumbnail)
price: $240
new year 2021

A single Rhodochrosite crystal which is a rather small thumbnail but is quite unusual, having a "melted" surface with etching and coming from an uncommon locality. This was collected in 1966 by Les Hitchings, he gives only Idaho Springs, Colorado as the locality, he collected three thumbnails there while on an extended trip, he was very proud of these pieces. The crystal is mostly transparent and gemmy, has good luster and a nice red color.
