Smooth, round black (dyed) Jasper with smooth, rondelle Miyuki gunmetal iris glass beads and Silver-Plated Stainless Steel Memory Wire; bracelet is one loop (with some extra for overlap). Jasper is 4mm; Glass beads are 2.25mm Bracelet is made with medium size Memory Wire (2.25 inches in diameter) 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
