Create your own set by choosing your size and number of bangles at checkout. Each bangle is approximately 1/5” wide and is made from solid sterling silver. Each bangle has been shaped and polished to sparkle. They are not connected, so they "clink" on your wrist. They are not adjustable and have a small solder seam to make a full circle. They will slide over your knuckles. To size, touch your thumb to your pinkie. Hold that position and wrap a tape measure around your knuckles. That circumference is your bangle size. The Sterling Silver consists of 92.5% Silver and 7.5% of an alloy, mainly consisting of copper. In some, the copper reacts with the skin and can turn it green. NOTE: Each bangle is in its natural state. It’s not coated with anything to prevent tarnish. Oils, lotions, moisture, etc. will accelerate the tarnish, so its recommended that you use a jewelry cloth for cleaning after wearing your bangle.
