Givenchy кристальный лариат, колье 16" + удлинитель 3"

This is a very nice necklace, stones are not actually navy, more medium to light blue but really pretty. Only issue is the foldover clasp, hard to fasten and discern if it is upside down or over the top fastener, then hard to remove, trying blind to feel which part of clasp to pull up to take off necklace.
