Author’s Note: This test and its answers were developed by myself (Rich Lund) and Theresa
Hubbard. All samples were identified by multiple members of Michigan lapidary societies,
having purchased many from such conventions/auctions. If any samples were ever in the
slightest doubt, we did not use them for the test. For the development of questions, and their
answers, multiple expert published sources were consulted. If sources reported varying
answers to questions we posed, we omitted such questions from the test. We did this in an effort
to be both fair and responsible to the students taking this test. Sources consulted, which at least
one of which will contain the answers supplied on this key were:
 Smithsonian Rock And Gem – The Definitive Guide to Rocks, Minerals, Gems,
and Fossils
 Peterson Field Guides – Rocks And Minerals
 National Audubon Society – Field Guide to Rocks And Minerals
 Simon & Schuster’s Guide To Rocks And Minerals
 Hermes House – The Complete Guide To Rocks And Minerals
One thing definitely noticed in doing the research to make this test is that not all “facts” about
minerals are undisputed. We certainly tried to avoid such disputes in order to make it a fair test.
However, we do apologize if a different “expert” source is consulted which shows conflicting
answers to our key. Should such a situation arise, we’d be happy to field any questions you may
have about the test and its answers. Please email such queries to: [email protected]
We hope that your test takers enjoyed this one and got a lot out of it!!!
