This just one more of my necklaces with interchangeable pendants. I made them that way by attaching a flexible "s" hook to the ends of each pendant. To change from one to another is a simple matter of twisting the top loop slightly and then attaching a different pendant to match your mood. BTW, the brilliant blue crystals are of the finest quality manufactured by Europe's most famous crystal manufactures. Alas, they no long make these crystal beads and forbid the use of their name, and even their country, in our ads. A simple search would reveal their name. The price listed is for the entire suite, but any combination of the necklace and a separate pendant is available for $40.
