Authentic Trollbeads Sterling Silver "Mexico" Dichroic Glass Lock/Clasp Retired - TAGBE-00029 Designer: Soren Nielsen This clasp left the collection in 2010. Mexico’s ancient history and its fascinating, colorful culture is reflected in this lock. In very good pre-owned condition. On one side, the dichroic glass reflects more of a blue-green and on the other side more violet - the colors are beautiful.
