This bangle measures 6 1/2 inches in circumference approximately. It is signed by the maker and marked 960 inside the bangle. 960 is a higher grade than sterling silver which is 925 parts per 1000. The bangle measures 1 7/16" wide approximately at the front as it measures down the wrist (36mm). The natural agate is a dark blue gray and burgundy with natural inclusions from the geode it was cut from on one side. This is not a flaw but rather an intrinsic part of the natural gem chosen to make this studio bracelet. Make offer welcome Phone not included The photos form part of the description. Like all colored stones there is a color variation that occurs in different lighting conditions both inside but also outside, even the time of day can make the color of a stone appear a little different. We do our best to show colors as we see them. Color perception is highly individual and some people can perceive more colors than others, also colors can appear somewhat different on different screens and devices due to variations in screen hardware and device display settings.
