My name is Renée Newman. I'm a gemologist (GG, GIA), lecturer, writer and author of 13 books on gems and jewelry. Besides providing details about my background and my books, this site offers information on gems, jewelry, appraisers, buying and selling. My goal is to provide consumers and jewelry professionals with unbiased, affordable information on how to buy, evaluate and appreciate gems and jewelry. But the consumer principles I stress in my gem books can also be applied to other subject areas such as health. In both cases, you should be informed, deal with competent professionals and get proper documentation. For more information go to my osteoporosis prevention website www.avoidboneloss.com.

My overall mission is to promote consumer issues, education, ethics, good health and the arts.


Diamonds: Their History, Sources, Qualities and Benefits. Unlike my other books, this is a hardbound, large format (9" x 11") book. This lavishly illustrated guide features hundreds of photos, maps and diagrams and covers everything from mining, geographic sources, cutting, antique diamond jewelry, price factors and manmade diamonds to the romantic histories of some of the world's most valuable diamonds.

A  revised and updated 8th Edition of my Diamond Ring Buying Guide was released last year with 131 new photographs, added chapters on silver and alternative metals, new information on lab-grown diamonds and diamond treatments, and updated information throughout the book. Unlike the Diamond Handbook which is geared to trade professionals, the Diamond Ring Buying Guide is directed to consumers and new jewelry salespeople. Click here for more information.
