This is a rare Copper Sulfide. This is the first time it has been found in Michigan. Analysis work was done by George Robinson of the Seaman Museum. A copy of the analysis will be sent. With possible Malachite and Calcite.

Currently sold out.

This is a new location for this mineral and the first occurence in China that I have heard of. Bright green thin needle-like crystals with good luster. Rather attractive. These vary in quality and so does the price. If you want a discount on 10, it would have to be on specimens all with the same price (then you would pay for 8). You will have to email or call to see about availability of quantities.

Bright blue Azurite scattered across contrasting white massive Quartz. The Azurite is just a thin coating with no crystallization. On some specimens, the Azurite is included in the Quartz. Most of the specimens also have massive Galena and some specimens have green Malachite. The specimens have been glued onto a foam base.

Bright green massive. Some specimens associated with massive Cuprite (specify if you want one of these). There are quite a few Cu minerals at this location, it is likely most specimens contain other species. Although listed as TNs, many are bigger than will fit in a TN box - if you want a smaller one that will fit - please specify - otherwise the persumption will be you want a larger specimen.

Bright reddish pink mixed with white. Fluoresence and Phosphorence similar to the old Terlingua Texas Calcite (I have seen this material sold as such). Bright reddish/pink under LW, bright light blue under SW. Phosphorescent under SW, a light blue even in a fully lit room - I know of no other phosphorescent material this strong. These have been washed in acid, which gives them a shiny appearance and brings out the color better. The following prices are for the acid-washed material - see S3 for natural)

Cleavages from the creation of Fluorite octahedrons. Sizes range from very small to 3 or more cm. Color of the Illinois specimens can be white, clear, amber, purple, blue, yellow and zoning of various colors. The Illinois specimens can have inclusions of Chalcopyrite, Barite and Bitumen and can fluoresce under LW either light blue or yellow. The New Hampshire specimens are green and fluoresce a vivid blue under LW. It is common to have cleavages shaped as equilateral triangles and occasionally three sided pyramidal shapes. These make great educational specimens for exhibiting cleavage and as hardness examples. These came from an octahedron chipper and were puchased in the mid 1990s. A mix will be sent with no guarantee as to size, shape, color or inclusions. In general, a little of each can expected and there will definitely be specimens from both locations nor will there will be all small pieces. The yellow and blue pieces are fairly scarce.

These are not natural crystals, but rather cleavages from larger cubic crystals. The result is regular octahedrons with 8 sides. All of the sides are the same length and the corners all have the same angle. These are great examples of cleavage in 4 directions and also ideal for hardness kits. I originally bought these in southern Illinois in the spring of 1996 soon after the last of the Fluorite mines closed. These are sold as a lot because there a mix of colors and a bit of variation of size. The average size is 12 mm on an edge or 16 mm across opposing corners. Colors range from white to clear to light purple to dark purple. Occosionally, interesting color zoning can be seen. Clarity ranges from opaque to translucent to clear. Each lot will have a mix of colors. It is possible there may be specimens with included Chalcopyrite, Barite or reddish Hematite (these are from a surface deposit). Also, a few of the octahedrons are fluorescent under long wave UV. The white and clear ones can fluoresce pale blue. Others have inclusions of bitumen (asphaltite) which fluoresces yellow. No guarantee is made regarding inclusions or fluorescents. If you have specific needs, then a special order can be made, but this will cost more for the time spent to fill the order. There are a few yellow and blue specimens set aside, but these are in high demand and cost 3.00 to 5.00 each. As soon as they are located in storage, other sizes of octahedrons will be made available.

This is not actually a valid species, but rather a distinctive bright green colored mica in the series between Muscovite and Celadonite which is also called Phengite. The color is a bright, Emerald green which contrast nicely with the white milky Quartz and an unidentified black material. The specimens have been glued onto white foam bases (I didn't do it).

Nice specimens. Found in a seam of Bitumen in Siliceous Limestone in Nov. 2009. Some have Quartz crystals; others just limestone. Here in Michigan, the quarry is better known as the Bayport Quarry. Bayport is the closest town of any size and is in the "Thumb" of the Lower Peninsula of Michigan. The area is also known for its vast farms of sugar beets. To get to the quarry, one passes by huge piles of beets at the Pioneer Sugar Plant. The quarry is also noted for a particularly nice form of Calcite. Locally called Root Beer Calcite, it is dark brown with iridescence (although recently I saw a piece of light brown Calcite with purple iridecesnce).

There is a choice specimen in the Michigan Gallery.

Brilliant red Cinnabar which contrasts nicely with enclosing white opaque Common Opal. Myrickite is an old name used by lapidarists for this material. It does take a high polish and makes quite nice cabs (of course these are small and only yield small cabs). There is some variation in color; a few specimens are a more orange color;pPlease specify of you want any of the orange colored ones. Glued onto foam bases.

This is something different, Ruby crystals from Los Angeles county. The location is in the mountains, just north of Claremont. The Corundum ranges from pink to reddish purple with many of the crystals complete and set in a white matrix. There are the following four other minerals found on these specimens which may vary from specimen to specimen: bright green Muscovite variety Fuschite, olive colored Titanaite which is a bit glassyand fairly scarce, micro, black, metallic Hematite crystals and in some specimens, light brown Phlogopite. Only Corundum is listed for the location on mindat, but someone who purchased one of these specimens saw one at the Culver City show (a suburb in LA) on which the other species were identified. Access to the location is quite difficult due to very rough terrain. The specimens have been glued to a foam base (I didn't do it). Collected by John Seibel.

Bright yellow Sulfur from just south of Detroit. There are both complete crystals and cleaved crystals available. All have etched surfaces. Currently, this Limestone quarry is closed to collectors and the zone being worked is not producing Sulfur. The TN sized specimens were self collected on 12/21/91 and July of 1993. The miniature specimens are from different collections from southern Michigan and date from the 1960s to the early 1990s. If known, the year or approximate year will be provided on the label. Price of the miniatures is dependent upon the completeness of the crystal, the size, and the brightness of the color. These make excellent educational specimens. However, because Sulfur is fragile, the boxed TN specimens are recommended if the specimens are to be handled frequently.

There iare choice specimens which are located in the Michigan Gallery and the Elements Gallery.

The Titantaramellite is found as small black crystals in a white matrix comprised primarily of Sanbornite and Kampfite. This is the type location for Kampfite, Macdonaldite and Traskite.

Currently sold out.

If you specifically want Macdonaldite and Traskite, please indicate this when ordering.

Really nice hopper growth crystals. These are not attached to matrix; apparently, due to the rapid growth. There are actually two mines at this location, the Pure Potential (formerly the North Geronimo Mine) and the South Geronimo Mine. I do not know which specific mine these come from (they are only appx. 600 m or 1800 ft apart). I got some specimens from Dave Shannon from the Pure Potential Mine in the mid 90s and these look very similar. There is an article on the Pure Potential Mine in Min. Rec. in 1996 vol. 27 p. 363.
