Four, yes count them, four ways to fidget with this head-turning necklace. The pendant sports a stainless steel rectangular charm that is smooth as a baby's you-know-what. It measures approximately 1-1/2 inches.  Dangling in front, is a pendant of four 6 mm Red Agate beads. They are snuggled close together, but they still have plenty of spinability. Red Agate is known for it's calming and stress relieving powers.  A good stone to have nearby when you need a little extra grounding. Rub the rectangle charm, spin the beads, mash the two charms together, or slide the pendant along the chain, you can't go wrong with wearing "Four on the Floor."  The pendant hangs proudly on a 30" ball chain necklace made of stainless steel and is tarnish and water resistant.
