(Press Release)
The American Society of Appraisers has announced its “Identification of Jade Treatments and Imitations, Quality and Value of Jade” course to be held on Thursday, Sept. 8 through Sunday, Sept. 11 in Boca Raton, FL.

Appraisers may be interested to know that fake jade material began making its appearance first in Hong Kong and then later at the Tucson and other gem shows in 2011. It’s marketed as “Canadian Jade” and looks similar to nephrite jade from British Columbia or jadeite jade, but it’s dyed quartzite that could be identified under magnification. This lecture and workshop will teach attendees how to screen for A jadeite jade (natural color), B jade (impregnated with polymer) and C jade (dyed) using only a UV lamp. There are limitations with standard instruments in testing jade, and when piece of Jadeite or Nephrite Jade is in question, it should be sent to a gem laboratory for advanced testing with VIS-NIR and infrared spectrometers.

To register or for more information, visit ASA online or call (800) 272-8258.

Wilkerson Helped This Jeweler to Navigate His Retirement Sale Despite a Pandemic

Hosting a going-out-of-business sale when the coronavirus pandemic hit wasn’t a part of Bob Smith’s game plan for his retirement. Smith, the owner of E.M. Smith Jewelers in Chillicothe, Ohio, says the governor closed the state mid-way through. But Smith chose Wilkerson, and Wilkerson handled it like a champ, says Smith. And when it was time for the state to reopen, the sale continued like nothing had ever happened. “I’d recommend Wilkerson,” he says. “They do business the way we do business.”
