Gold Technology Magazine

Our jewellery technology magazine, Gold Technology, ceased publication at the end of 2002. As its contents remain valid and useful, we are putting all 36 back issues into the Archive over time. This will serve as useful reference materials for jewellers interested in obtaining a better understanding of jewellery materials and manufacturing technology and Best Practice.

To assist you in locating articles of interest, you will find an Index of articles below. Those articles in the archive can be accessed directly on this website. Those earlier issues not archived can be obtained as photocopies directly from World Gold Council in London

If you wish to view each issue of Gold Technology in its entirety, please use the archive list of issues on the right side of this page. For each issue, click on the Union flag for the English language edition or the Italian flag is for Italian language edition.
