House of Harlow versatile double sunburst medallion necklace in taupe

This necklace is so unusual. One medallion is fixed in place and the other slides around so it can be worn multiple ways, including having the small medallion on the back of your neck and the large in front or both together. Necklace is 15” long. Large medallion is imperfect and missing a sparkle - please see pictures. Otherwise is good condition.
