Black & White Striped Shells Necklace

Those sparkly little 2mm round jet beads #5000 set off the bold black and white striped shells with highlights. Vintage Vendome beads in gold with a pebbly surface bring a touch of glamour. You'll likely not guess where I bought these beads...the Swarovski store in London...who would think one would find them there. I couldn't resist them and cleaned out the last package. If anyone knows the name of these shells or where they came from, please email me at dmfbeads@bitstream.net. Thanks!
