Out of thousands of rock types and mineral species on Earth, there are only a few special types that have earned the label "precious". Throughout history gems have been perhaps the most alluring and concentrated form of wealth sought by man. This set presents a collection of six polished gem stones and one precious metal in a 5 by 7.5 inch snap-close plastic display case, along with an in-depth, 4-page fact sheet with photos of each stone as a finished gem. |
| MINIMUM ORDER TOTAL MUST BE $15. All of the Jensan Scientifics study materials have been reviewed by qualified scientists and educators, and no matter what size the set, information sheets are always included. The details of rock and mineral sample selections are proprietary to Jensan Scientifics. For individual questions, we welcome e-mail or calls!
