EBay Extends ‘Authentication Service’ to Fine Jewelry

EBay expanded its “authentication service” to the fine jewelry category, having previously introduced it for sneakers, watches, handbags and trading cards, said the company Wednesday. EBay will collaborate with the Gemological Institute of America to make the service available for eligible new and pre-owned fine jewelry sold for $500 and up, it said. GIA experts will perform a multipoint inspection, verifying metal type, purity and gemstone quality, “to confirm the authenticity of every eligible item,” it said.
