The high bidder gets the pair. These come with 14kt gold filled butterfly clutch backs. I do have solid 14kt backs for an additiional fee if wanted please email. These are soooo nice, you will be very pleased. Please check our other auctions here and at debsbeads on ebay for more vintage swarovski and other natural stones. Thanks, Pete
