eBay's Luxury Exchange: How it Works: Shoppers have their luxury items appraised and assigned a value with which they can shop the store's inventory of designer watches, handbags, and jewelry. Once shoppers find an item(s) within their "currency," they can make the exchange and walk out of the store with their new luxury goods. If nothing in the store catches a shopper's eye, guests can visit the on-site photo studio and opt to list on eBay themselves instead of exchanging.

The Luxury Exchange comes on the heels of the expansion of Authenticity Guarantee to jewelry, a move that significantly augments eBay's luxury offering. eBay launched Authenticity Guarantee in 2020, and the program now includes sneakers, watches, handbags, trading cards and now, fine jewelry. As a result, more and more shoppers are turning to eBay to buy and sell their collections.

This behavior is reflected in the depth and quality of inventory available on the marketplace.
