Renée Newman is a respected gemologist and author of several guides on gems and jewellery. Her books are used throughout the world as buying guides, sales-training tools, class texts and references for jewellery professionals.

“Rare Gemstones is a fascinating insight into the latest and more unusual gemstones that are now finding their way into designer jewellery. The book covers rare gems that are mounted in jewellery, as well as some that are used only very occasionally, based on the opinions and usage of a range of jewellers. From their suggestions, over 60 of the lesser-used gem materials have been selected, documented and presented in a highly visual way. In total, the information given in this book is very well presented, easily readable and accurate, ensuring an excellent point of reference in an area all too often overlooked. Whether a newcomer to the world of gemmology or an experienced collector, this volume has something for everyone, and is highly recommended.” - Gems & Jewellery, Spring 2012

When you need it, the information will be on your bookshelf ready to help you figure out that rare stone, or explain it to your client. Everyone wins.” - Reviewed by Kim Piracci, GG
