Renée Newman developed her interest in gems while conducting tours to Asia, South America and the South Pacific. Her passengers wanted information about the gems displayed in hotels and stores so she signed up for a colored stone grading course at GIA in order to answer their questions. The teachers there inspired her to complete the GIA colored stones and diamonds program.
After receiving a graduate gemologist diploma from the GIA, Renée was hired as a gemologist at a diamond wholesale firm in downtown Los Angeles. It provided hands-on experience grading diamonds and selecting colored gems and pearls for their jewelry. Armed with trade experience and gemological credentials, Renée decided to create books that showed readers how to visually evaluate the quality of gems. Her first book, the Diamond Ring Buying Guide, was published in 1989. Since that time, she has written 13 more books on gems and jewelry, including the Diamond Handbook geared to trade professionals and her new large-format book Diamonds: Their History, Sources, Qualities and Benefits. Information about it is at www.reneenewman.com/diamonds.
Renée’s books are used as consumer guides, gemology course textbooks, sales training tools and appraisal references and are listed at www.reneenewman.com/books.htm.
Lisa Elser living in the Vancouver, BC area. She spent 25 years in IT working for companies like Bell Laboratories, NCR and Sun Microsystems and consulted to some of the largest banks and insurance companies in the world.
Lisa holds Bachelors and Masters degrees from Rutgers University, as well as advanced courses on Finance from Edinburgh School of Business. She has lectured around the world on using technology to achieve business goals and was a sought after speaker for conferences and corporate meetings.
She began cutting gems as a hobby when she moved from consulting to managing consultants, finding that it gave her a satisfaction to create something with her own hands.
Lisa trained in gemcutting in Montreux, Switzerland and did her Graduate Gemologist degree with the GIA in Carlsbad, CA. After a number of years of cutting as a hobby she retired from IT and with her husband Tom founded Custom Cut Gems. Lisa now works with custom goldsmiths and jewelry designers in North America and Europe. She and her husband travel the world to buy rough gems. As the business grew, she and Tom began making grants to support economic development in gem producing countries. They continue to put a percentage of the profits into projects like well, sanitation, women’s business cooperatives and education.
She’s published articles on topics including rough buying techniques, sawing, faceting “off the diagram” and on the heat treatment of tourmaline. In addition to her own publications, Lisa has been featured in More Magazine, Jewellery Business Canada, The Gem Guide, and her work appears in Renee Newman’s “Rare Gemstones.”
In 2013, she won the a prestigious American Gem Trade Assoc (AGTA) Spectrum award for her 14.24ct red Tourmaline. The gem is now in the permanent collection of the Smithsonian Institution.
