Authentic - purchased by me in the early 2010’s at the Tiffany & Co. store in Michigan. Currently retailing in Tiffany HardWear collection for $575. This was a favorite of mine for so long, I just don’t wear many bracelets anymore. Features 17 sterling silver beads (I believe they are hollow) strung on a silver chain with a lobster claw clasp. Clasp has the Tiffany & Co. tag with 925 on the back - very small and hard to capture in photos. Great condition! Was worn a lot but always kept in the bag and box when not on my wrist! Approximate measurement: 7 inches long (perfect size for super tiny wrists!) 3/8 inch balls
