This week's update consists of 21 mineral specimens, 15 thumbnail specimens and 1 new entry to the Study, Hobby and Bulk Samples listings. The next update will be available on Tuesday, Febuary 28nd, 2012 and will be available by 12:00 EST (5:00 GMT). This is a day earlier than usual. This is because I will be traveling to Richmond, Indiana to do a show and will be leaving Wednesday afternoon. Any minerals ordered after 2:00 PM on Wednesday, the 29th, will be shipped when I return home on Monday, March 5th. While gone, it may take a while to respond to email. While in Indiana, I will be staying at Harris Precht's farm. He has no internet access at the farm, but there is wifi at the show. After next week, there will be a resumption of updates available every Wednesday at noon.

S42 Fluorite Octahedrons, Small size: Cave-In-Rock, Hardin County, Illinois

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.
