Silver mother of pearl necklace with Swarovski crystals in Charleston, SC

I bought this necklace several years ago from Hand In Pocket, a boutique in Atlanta, Georgia. This necklace has never been worn and has been stored in the box that it was purchased in. I have not had this necklace evaluated or appraised, so I am going on the description on the tag created by the boutique. The tag says "Silver double strand mother of pearl w/ Swarovski crystals". Hand In Packet is a reputable boutique that is searchable on the internet.
