THESE HAVE A 3 MONTH TAT! They are made to order and each are handmade by me. 
The turquoise is authentic, matrix may vary since they are natural stone. Bezel cups and rope border are sterling silver. The buckles themselves are NOT silver. 
Not responsible for sizing errors. Birkenstock Gizah are the footbed style these are built on.
