Huge purple agate, silver pendant

This big, bold, boho authentic agate pendant is just under 4" long. It's a beautiful deep purple color, and is set in fine sterling silver. It's stamped "Charles Albert Fine Silver" inside the bale. This pendant can be worn with either a long or short chain for different style effects. This listing is for the pendant only. The matching ring is also listed in my closet. In excellent vintage condition
