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.
