Mixed metals it is.
This necklace is a midway point. A moon form in the golden hoop becomes the frame for three quartz crystals. The three Fates, the Morrigan, the state of time. All of the elements tied together with the moon metal, silver.
This necklace can be worn long or short, the longest length is 20 inches, then you can pull the chain through the hoop and make it however short you need by linking the clasp on any link.
14/20 Gold-fill, sterling, quartz
