GCAL Expands Role In Education Through Speaking Engagements And Presentations

NEW YORK, NY ― September 7, 2007 ― In keeping with its mission to inform jewelers about the latest gem lab technologies and services available and stress the importance of integrity in diamond grading, Gem Certification & Assurance Lab (GCAL) has ramped up its visibility on the industry lecture circuit – and it will continue to make its members available to give presentations as featured speakers at key industry meetings, trade shows, conferences and other events.

For instance, Don Palmieri, President of GCAL, addressed key issues such as the latest gem lab innovations and ethical responsibility at the Arizona Jewelers Association’s (AJA) Annual Convention on Aug. 11.

In his presentation, Mr. Palmieri explained how cutting-edge lab innovations such as GCAL’s Optical Brilliance Analysis, GemfactsSM Digital Certificate, Gemprint TM and “silent salesperson” Electronic Certificate systems boost the consumer’s confidence, knowledge and appreciation of diamonds – and also bring a value-added element to consumers that can enhance a retailer’s brand name and lead to higher sales.

Mr. Palmieri also discussed why gem laboratories need to take full responsibility for their work, and the difference between a diamond grading certificate, as opposed to a diamond grading report.

“With recent industry studies suggesting that nearly 50% of consumers mistrust jewelers, integrity has never been more important to the industry – particularly in the diamond sector,” Mr. Palmieri said. “While most labs issue diamond grading ‘reports’ full of disclaimers, GCAL issues ‘guaranteed certificates’ under our unique Zero Tolerance Consumer Grading Guarantee, which offers a cash-back policy ensuring the accuracy of our cut, color and clarity grades, as well as the carat weight, on all GCAL-graded diamonds. In addition, GCAL is the only diamond laboratory part of a publicly traded company and therefore subject to reporting requirements of the United States Securities and Exchange Commission and the internal control requirements of Sarbanes Oxley laws and regulations.”

According to Craig Lynch, G.G., Vice President of AJA and owner of Ouellet & Lynch Appraisers in Phoenix, AZ, the group chose Mr. Palmieri to speak at its Annual Convention because of GCAL’s unparalleled guaranteed grading certificates, as well as Mr. Palmieri’s 40 years of experience as a consumer advocate and well-known proponent of industry ethics. And the approximate 80 AJA members in attendance for the presentation were not disappointed.

“Most of our people were surprised at the state of the industry – they never realized that all gem labs do not stand behind their work to the same extent, but Don’s presentation really opened their eyes,” Mr. Lynch said. “Our members also were very impressed by the innovations GCAL has come up with, and with Don’s responses to their questions about diamond grading and grading standards. Don’s presentation probably was the most well-attended lecture of our Convention.”

GCAL also recently gave a presentation to the National Association of Jewelry Appraisers (NAJA) that received rave reviews. Daniel Gillen, GCAL’s Lab Director, and Sharrie Woodring, GCAL’s Vice President of Product Development, gave a two-hour lecture entitled “Diamond Grading Secrets” at NAJA’s 28th Annual Mid-Year Education Conference, held in conjunction with the Atlanta Jewelry Show on Aug. 12.

Mr. Gillen, one of the world’s foremost diamond grading experts with 27 years of experience, offered the 100+ NAJA members in attendance tips about the grading process, how to select and optimize your equipment, best-practice procedures for grading polishing and symmetry, and advanced techniques for color and clarity grading.

“Dan and Sharrie made a great team,” said Gail Brett Levine, G.G., Executive Director of NAJA. “We asked our members to complete a Conference evaluation form for each of the 14 speakers that gave presentations, and Dan had more ‘excellents’ than any other speaker. His information was well-presented, offered great grading points that were sorely needed to help our people improve their businesses, and was really well received by our members.”

Also in September, Lioudmila Tretiakova, Ph.D., GCAL’s Senior Research Gemologist, will be giving a presentation entitled “Spectroscopic Methods for the Identification of Gem-Quality Natural Diamonds” at the 6th European Conference on Mineralogy and Spectroscopy at Uppsala University in Sweden on Sept. 10.

Meanwhile, Mr. Palmieri will represent GCAL in a four-lab presentation during the Virginia Jewelers Association’s Annual Convention on Sept. 30. Members will hear Mr. Palmieri discuss GCAL’s strict grading process and unique products and services.

Members of the GCAL team are available to speak at upcoming industry meetings and events.
