The Vortex Medallion pendant on an 18" silver or gold-colored metal chain in your choice of ring colors. The pendant itself measures approximately 1 inch in diameter. Select one color for all of the large rings and one color for all of the small rings.
 
Note: most of the ring color examples show the pendant on the black cord, but this listing is for the silver or gold-colored metal chain.
 
All of the rings are anodized aluminum. Sometimes the anodization process results in slightly different shades from batch to batch. Colors are marked with a plus (+) sign when this variation in shade is noticeable.
