Smooth, round silvery black Silver Obsidian with smooth, rondelle shaped Stainless Steel beads, lobster clasp and oval chain; made with Soft Flex brand wire Obsidian is 4mm and 6mm; Stainless Steel is 4mm Bracelet is 7 to 7 1/2 inches long; when bracelets are made with beads larger than 5-6mm, you may need a little longer length bracelet than you normally wear, depending on how loose/tight you like your bracelet. Note: All pearls/stones may slightly vary in color, shape, and size because they are real/natural pearls/gemstones. Some pearls/stones may have been dyed or heated to enhance their color. I do my best to match all pearls/stones for color, pattern, shape and size. All pictures are taken in natural light. Colors may vary slightly when viewed on different screens/devices.
