The center stones in this bracelet are Black Silk Stones. Black Silk Stone is a natural stone with a white/tan background with black ribbons running through it. I then used black and metallic glass beads around it. For the edging, I used black Swarovski crystals. The clasp is a beautiful gun metal plated brass clasp with a wonderful scroll design on it. It's a push tab style clasp. Squeeze the tab for release. It can be done one handed. This looks great with almost any outfit! Wear it with your little black dress, or your black tee shirt with jeans. The length is 7". This is a small to average size. I can lengthen the bracelet upon request with purchase. Shipping is free in the USA.
