The Vortex Medallion pendant on an 18" black flexible cord 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.
 
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.
 
If you want the colors in this pendant arranged in some other pattern, message me, and I'd be happy to work with you to make what you are looking for.
