Books

Gemological books are a goldmine of valuable information that give us more insight into the world of gems and diamonds: from its mining to its manufacturing processes, to the detection of its treatments, and its many forms and imitations. We have carefully curated books that bring significant contributions to the various gemological and jewellery communities around the world. Most of these books are sourced from original research by Branko Deljanin, having worked in 3 major laboratories in North America, and collaborating with other world-renowned international gemologists.

*If you would like to have a book personalized with an autograph by Branko Deljanin, please indicate it under the NOTES section.
