Brass Filigree Set Opal cabochon

I found this blue cabochon at the Tucson show in February 2010. I used Vintaj findings to bezel it and make a bail for it. The necklace part is herringbone chain made with Toho Treasures 22L and inserts of Swarovski crystals in zircon complete the materials.

I like magnetic clasps because they are so easy to use. So there is no beaded toggle clasp and button for me.
