This one necklace incorporates my 2 favorite stones, moonstone and labradorite. There is one clasp that anchors these 2 lovely necklaces and it is adjustable by 1 inch, making the short necklace 16-17 inches and the longer necklace 18-19 inches. The shorter pendant is a round moonstone and the longer necklace is a square labradorite, both measuring a half inch or less in both directions.
