A Word About Specimen I.D.

You probably know that it's impossible to guarantee the chemical composition of a mineral specimen without X-ray diffraction or fully-quantitative EDS analyses.  These methods, of course, are time consuming and costly.  It is our goal to provide affordable minerals;  the cost of analyses to confirm questionable ID's would add considerably to the price of a specimen.

However, you can buy with confidence from this site, because

(1.) any time there is a doubt as to identity, this will be indicated clearly in the description of the specimen (e.g., with a question mark, etc.), and

(2.) all rare species offered as such are "what the label says, or your money back" (according to our return policy; please see order info for details).

The degree of certainty of a mineral's I.D. must be evaluated on a case-by-case basis (depending on origin of the specimen, among other factors) - and this will be indicated when appropriate for a mineral specimen.

Whenever there is considerable doubt, a mineral will be sold as UNIDENTIFIED or something to that effect.  This practice may not appeal to some, but consider the prices involved. A $4.00 specimen would no longer be $4.00 if it had to be put through XRD / EDS analysis.  Even rudimentary chemical analysis is time-consuming, and we don't normally have time to do this for unknowns.
