This silver-plated adjustable ring features a 17 x 9mm diamond-shaped purple druzy crystal. Druzy, which is also known as druse or druze, refers to the coating of tiny crystals which have grown on a base such as rock. This particular piece appears to be lab-grown rather than natural. The band part of the ring is 2mm wide, and is adjustable by slowly and gently squeezing or pulling until the desired size is achieved.
Please remove rings before washing your hands, or otherwise getting them wet.
