We sell mineral specimens in micromount size only.


A micromount is a mineral specimen that is permanently mounted in a box and requires magnification for proper observation. The size of the box varies from one country to another, and isn't really important. Better to mount in a "non-standard" box than to risk damaging a fine specimen. Many collectors do not mount their specimens permanently, and are then said to collect microminerals, rather than micromounts. The specimens are the same.



The smallest crystals are generally the most perfectly formed. This stands to reason. Since the smaller the crystal, the less likely that it would grow into the other side of a vug, or be deformed by some other means.


Some species are known only in micro size.


Good micromount material is only a fraction of the cost of cabinet specimens of the same species and quality.


A micromount collection doesn't take up much room. 1300 specimens, mounted in US standard boxes, will fit in a 25 X 25 X 25 cm cube. Of course, if you accumulate a lot of duplicate material by field collecting, etc., all bets are off!


You don't have to spend a lot on a microscope. Since 30X magnification is usually adequate, you can find a new 'scope for under $500.00, and a used one for less. A binocular scope is best, to get a "3-D" effect. For that matter, you don't absolutely have to have a microscope. A hand-held lens might do for a start (although it sure is tricky to mount a specimen with one hand, while holding the lens with the other). Some interesting ideas on using a hand lens can be found in an article on "Cheap Microscopy". Another good article on micromounting, including techniques, is Micromount? By Pierre Gatel, now available in English. See also my article on mounting moisture-sensitive minerals. For more on why micromount, see Tim Jokela's "10 Top Reasons…"

Another useful list is my list of Conditions Harmful to Mineral Specimens.


We sell mounted and unmounted micromount material, and only micromount material.

We have something for almost everyone- some specimens are priced under US$1.00, for beginners and those who might be interested in different localities for common species. There are also rarer and more unusual specimens, at higher prices. Over 300 items are listed, with more being added all the time. Click here to see the price list

Satisfaction is guaranteed. Click here for our Terms of Sale and How to Order.


All the resources of the web can not take the place of a good local club for exchange of both specimens and information.

I've tried to list here all the micromount groups or clubs with micromount subgroups that have either a website or E-mail address. For clubs that aren't on line, check the International Directory of Micromounters, published by the Baltimore Mineral Society, Inc.
