I don't know about you, but I find these clear quartz nuggets to be very intriguing. Natural quartz rock crystal is a very hard stone (Mohs hardness of 7.0) and has a very high refractive index, making these do interesting things to the light. Some of the nuggets contain tiny inclusions. They alternate with silvertone balls. The bracelet is 7.5 inches long with an internal circumference of 6.25 inches when fully closed; it expands another inch with the extender chain.
