Please read this before bidding! Micromounts are specimens which require magnification (sometimesa lot) for proper appreciation, so please be aware of this when purchasing and read the measurements of the specimen carefully to make sure you know the size of what you are ordering. Many of these specimens will not look like anything of value without good magnification!! Thumbnail specimens are specimens that fit in a 1.25 inch (~3.3cm) plastic box, which should give you an idea of scale. Calcite Up for sale is a 7.8x6.3x3.8 cm cabinet specimen of crystallized stalactitic Calcite from the Santa Eulalia District, Mun. de Aquiles Serdán, Chihuahua, Mexico. It fluoresces bright chartreuse green under shortwave UV, and a weird dull yellow under longwave. It phosphoresces as well. A very handsome piece from one of Mexico's top specimen producing areas.

Contact me if you are interested in selling your collection of rare or unusual mineral specimens.A note on IDENTIFICATION of rare species: unless I state otherwise, identifications of species are based on mine or my source’s visual inspection of the specimen. I don’t think most people bother to say anything about it, but this is normal with rare species, and you shouldn’t be fooled into thinking that just because someone says that’s what it is, that they are right. A knowledgeable collector with a good photo library and a good microscope can do amazingly well, but there is always a chance they are wrong. Even if a specimen has been analyzed by EDS, there is still often some uncertainty, as this technique only tells the elements present in the sample and perhaps the rough formula if the measurement goes well. It provides no data on the structure. I will try to note when there is significant uncertainty into the ID of a species. If you think one of my ID’s is wrong, please let me know, so I can try to check it! Thanks for looking. Please check out my other auctions.
