EBay Expands Authentication to Jewelry with GIA Partnership
New and pre-owned jewelry sold for $500 and above will be eligible for the authentication service.

The authentication service was introduced in 2020, rolling out to watches, sneakers, handbags, and trading cards.
Now, eBay will authenticate new and pre-owned fine jewelry sold for $500 and above, including designer jewelry from Bulgari, Van Cleef & Arpels, David Yurman, Cartier, and Tiffany & Co.
GIA experts and gemologists will verify the fine jewelry, authenticating the metal type, purity, and gemstone quality.
“Jewelry has always been a popular category on the marketplace, and its growth shows how consumer demand is only increasing,” said Tirath Kamdar, general manager of luxury at eBay.
EBay’s jewelry category has grown significantly over the past year, said the company.
Sales of Bulgari, David Yurman, and Van Cleef & Arpels were all up double digits month-over-month in May, while purchases of fine jewelry from brands like Chopard, Harry Winston, and Hermès rose 38 percent year-over-year in the past six months.
In 2021, eight pieces of jewelry were bought on eBay every minute, said the company, for a total of 4.2 million fine jewelry items sold. There are 7.8 million fine jewelry listings, on average, on eBay every day.
The herringbone style is doing especially well, said eBay, with bracelet sales up 48 percent year-over-year and necklace sales up 26 percent.
“As we continue to listen to our community of luxury enthusiasts in order to foster an even more trusted shopping and selling environment, expanding ‘Authenticity Guarantee’ to jewelry was a crucial next step for our luxury business,” said Kamdar.
When a shopper purchases jewelry with an “Authenticity Guaranteed” badge, that item is sent to GIA for a multi-point inspection.
When verified, it’s shipped to the customer with a unique authentication card with a QR code.
Buyers can scan the code to access the jewelry’s documentation and learn more about the piece and the authentication process.
If an item can’t be verified or is not consistent with the listing description, it’s returned to the seller and the buyer is issued a full refund.
If the buyer returns the item, it will first be inspected by GIA experts before being sent back to the seller.
“GIA is the trusted independent source of knowledge, standards, and education in gems and jewelry; our mission is to protect consumers,” said Pritesh Patel, chief operating officer of GIA.
“Collaborating with eBay on its Authentication Guarantee extends our mission, helping to protect the millions of eBay fine jewelry buyers and sellers.”
Prior to its current Authenticity Guarantee service, eBay offered a similar vetting service called “eBay Authenticate,” which rolled out for jewelry in 2018.
“Once fully rolled out, Authenticity Guarantee for jewelry will encompass more inventory than the initial service (eBay Authenticate) and is free for both sellers and buyers, as opposed to the seller taking only a percentage of their item’s final selling price,” explained a spokesperson.
“Authentication has always been crucial to jewelry, but it was equally important to us to figure out how to offer it in a way that encompasses a plethora of styles, items and brands at accessible price points so that it benefits as many sellers and buyers as possible.”
EBay said it has authenticated more than two million items since launching the Authenticity Guarantee service and expects to exceed five million in the next two years.
