Sterling Silver, 24 & 22K gold, Iron included Quartz. This amazing stone has thin layers of iron (the yellow and orange) running through clear quartz.  The "pebbles" on the element beside it are sterling with 24K gold fused to them (PLEASE SEE THE VIDEO THAT SHOWS HOW TO PUT IT ON AND GIVES A SENSE OF THE SCALE)  It measures 1-1/4" across the top of the ring.  It has a "U" shaped shank that is 1/2" wide at the bottom, that allows for sizes 7-1/2 to 8-1/2 closed up but will accommodate a larger size as it is open (not soldered) in between the silver part and the stone.  EXCHANGES ACCEPTED 10 DAYS FROM RECEIPT
