May Emerald Swarovski Birthstone Collection Charm.
The Swarovski crystals are cut with water which makes then sparkle and shine in ways standard and traditionally cut crystal simply can't achieve.
Birthstone charms can be added to either the Birthstone Bracelet or Necklace. See below. Alternatively, if your current charm bracelet has individual clasps then these Birthstone charms will hang properly next to the rest of your collection.
