With five loops hidden beneath the butterfly wings, you have plenty of design options with this whimsical clasp. Properly balanced, you could use just the middle ring for a single strand, or any of the other rings for a two, three, four, or five strand necklace. The head of the butterfly pulls up and the two wings separate to open the clasp. The stylized circles on the wings are representational of the intricate patterns found in nature. There is a heart hidden on each wing. This clasp is sterling silver and was hand-made in Istanbul. The highest part of the wing is 22 mm. The clasp is 39 mm wide at the widest point. The five rings are fairly close together with about 1 mm between them. It weighs 10.3 grams.
