A quiet, yet rumbly roller, this dangly pendant is fun to fidget with. Four small stainless steel rectangles turn individually and together. They measure 7x3 mm each and the smooth edges really have a nice tactile quality. The pendant is finished with an 8mm Hematite bead that turns independantly from the rest of the beads. Hematite is best known for its grounding and calming effects and can be helpful to bring about focus and concentration. The chain is a 2 mm, 20-inch flat cable stainless steel necklace with a lobster claw clasp. The necklace is water resistant and will not tarnish.
