Huanghoite-(Ce)
stock #ALEC-15-296
Bayan Obo Deposit - Baotou League
Inner Mongolia Region, China
4.4 x 3.2 x 1.8 CM (miniature)
price: $110
Fall 2015

An unimpressive but rare mineral from the type locality. This is a Barium analog with Synchysite-Ce and is associated with other REE minerals. This specimen is intermixed with Fluorite and what looks like Parisite but not confirmed. The area of Huanghoite is sizable compared to others. Ex Shields Flynn collection.
Barite w. Quartz overgrowths (sugar cube habit)
stock #ALEC-19-189
Murray mine, Sugarbowl pocket, Independance Mts. District, Elko Co.
Nevada, United States
8.3 x 4.5 x 3.4 CM (cabinet)
price: $360
Fall 2015

A very clean and sparkling specimen from the one time find of "sugarcube" habit Barites. In fine condition, this displays well from several angles and has a slightly grey color on some faces with a more white on others. The largest crystal is 3.5 CM across. Choice.
Cassiterite on Muscovite w. Fluorite and Arsenopyrite
stock #Alec-12-135
Yaogangxian Tungsten Mine, Yizhang County
Hunan, China
3.6 x 3.3 x 2.1 CM (miniature)
price: $70
Fall 2015

Shiny twinned Cassiterite crystals sit on a Muscovite matrix that also hosts some Fluorite and Arsenopyrite crystals. From the Yaoganxian (YGX)mine, Cassiterite is an uncommon mineral in good crystals. This has a few dings but still looks quite good for the locale. YGX was for years the most important classic and collected locale in China but it is now nonworking.
Bismuthinite inside Fluorite on Arsenopyrite
stock #Alec-15-243
Yaogangxian Tungsten Mine, Yizhang County
Hunan, China
4.2 x 3.2 x 2.5 CM (miniature)
price: $285
Fall 2015

A attractive miniature with a prominent Fluorite cube that is densely filled with needles, hairs and curls of metallic Bismuthinite. Since the Fluorite rests on a well crystallized cluster of Arsenopyrite, the overall contrast and esthetic structure is excellent. As with many fine Yaogangxian specimens, there are many associated species, this has Sphalerite, Stannite and Quartz. Better in person, this is an older specimen from the Shields Flynn collection.
Arsenbrakenbuschite with prismatic Mimetite, Tsumcorite? and Descloizite
stock #13.1-040
Mina Ojuela, Mapimi
Durango, Mexico
8.8 x 6.5 x 3.9 CM (cabinet)
price: $320
Fall 2015

Cabinet specimen well crystallized with many prismatic gemmy hexagons of Mimetite to about 8MM that are set on and mixed with yellow to orange tufts of Arsenbrackenbuschite. The prisms of Mimetite are a more rare habit at Ojuela. There is also what seems a perfect match for Tsumcorite (which has also been found in this assemblage), but this was not tested. A few Mimetites have some damage (not seen by my naked eye) but most are perfect with a yellowish to transparent grey color. This would make many thumbnails and micro specimens if split up. As is, a rich cabinet specimen for these rare minerals.
Calcite w. Marcasite & Dolomite
stock #ALEC-17-1073
Benchmark Quarry, St. Johnsville, Montgomery County
New York, United States
4.7 x 3.2 x 2.9 CM (miniature)
price: $95
Fall 2015

Amber colored Calcite crystals are prominently perched on a crystallized Dolomite matrix. In fine condition with rich color and above average clarity, this was collected by Bill Hladysz many years ago. The Benchmark quarry is now something of a modern NY state classic locality. Affordable and pretty.
Calcite on Marcasite w. Dolomite
stock #ALEC-17-1074
Benchmark Quarry, St. Johnsville, Montgomery County
New York, United States
4.8 x 3.1 x 2.3 CM (miniature)
price: $45
Fall 2015

Very cute, affordable and in good condition from the Benchmark quarry collected by Bill Hladysz many years ago. A single Calcite prism is perched on a Dolomite and Marcasite matrix with a few micro Pyrites as well. These are modern NY classic specimens.
Calcite on Dolomite
stock #ALEC-17-1072
Benchmark Quarry, St. Johnsville, Montgomery County
New York, United States
5.5 4.3 x 2.5 CM (cabinet)
price: $65
Fall 2015

Very cute, affordable and in good condition from the Benchmark quarry collected by Bill Hladysz many years ago. Three individual Calcite prisms are perched on a crystallized Dolomite matrix.
