New York—For the next two months, the latest diamond screening devices will be available for members of the industry to test, thanks to an event spearheaded by the Diamond Manufacturers & Importers Association of America.
DMIA’s Diamond Technology Showcase kicked off Tuesday at the organization’s headquarters in New York City’s Diamond District.
The event gives DMIA members, as well as members of the industry at large, the chance to familiarize themselves with many of the devices on the market created to distinguish natural diamonds from lab-grown diamonds and diamond simulants.
They can test their own diamonds and diamond jewelry using the devices and will have the chance to connect with the instruments’ manufacturers.
“Screening equipment must become an integral part of the process of buying and selling diamonds,” said Stuart Samuels, who was elected DMIA president earlier this year. “Today, it is an essential tool, just like a diamond scale.”
Those interested in attending the showcase must make an appointment.
They can do so online here, or by emailing the DMIA at appointment@dmia.diamonds and providing the number of attending participants along with their names, company names, email addresses and telephone numbers.
