Smooth, round grayish Blue Matrix stone with silver matte Czech glass rondelle shaped strung on two ply, strong dark gray colored Brazilian Waxed Cord Matrix Stone is 6mm; Glass is 2mm Bracelet is large and can be adjusted from approximately 7 1/2 inches to 8 1/2 or 9 inches. This bracelet will need to slide over the largest part of your hand and then can be tightened once it's on your wrist. 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 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.
