Following are illustrations from a German textbook that were reproduced as part of a gemology correspondence course.

Important Note

These pages from a German text-book are being sent with Table No. 14 so that you may be able to get an idea of the appearance of certain gem-stones of which you may have never seen actual specimens. Some of the many less important species not listed in Table No. 14 will be noticed in the portfolio.

Later on in the course, with the table of all gem varieties which accompanies Assignment No. 20, you will receive a set of color plates which are printed in more authentic colors. Much of the color work in this portfolio is not especially "true" as you will see in some of the varieties with which you are familiar. These colors are not sufficiently clear or "transparent" to accurately represent them. However, the colors are near enough to the accurate colors to give one who has not seen specimens of that variety a sufficiently accurate visualization during this early introduction to the course. Please remember this, and after you receive the accurate color plates use this portfolio only as an auxiliary reference to remind you of the approximate colors of certain lesser known varieties not shown in the later color plates. We recommend that these not be relied upon to interest customers in gems as they fail to do justice to the beauty of color which these gems actually possess.

The word opaque after a name is to help you in visualizing the stone as not being transparent. Opaque, translucent and other degrees of transparency will be studied in Assignment No. 11, but are briefly explained in the Glossary which accompanies your next assignment.
