Both necklaces are in good condition and kept in a clean smoke free home. Both tested in the quartz, amethyst , citrine category on my presidium II. Average bead approximate 5mm. One is 24” and other 20”. They are not identical necklaces. The beads are more translucent on the longer one. Possibly less use and a younger necklace and/or a little different in composition. #gemstone #necklace #purple
