There are many books written for this industry, some title's difficult to find in bookstores.
Many bookstores don't have this tittles listed, not available. It is not commercial, to sale or stocks them; there are only few readers and buyers.
These books are important to our industry, they help us to under stand, to improve and develop us for a better.
For this reason we list this available bock with the authors name. No other information available at the moment.
For sure this list is not complete, should you know some tittles which are no listed, forward this information and we are more than happy to include them.

Additional information we could list:

•  E-mail of author
•  For each title, bookstore which carry it
•  Detail of some contains

If they author or the bookstore, which carries it, is interested they can supply use with this information and we will add it to our listing.

To a later date we can list them additional, by subject like:

•  Gem
•  Color & light
• Jewelry making
• Jewelry style (design)
