semi precious stone and fresh water pearl necklace

This is a one of a kind custom made necklace designed by me. The fresh water pearls and semi precious stones I picked out a few years ago at a jewelry store in South Africa brought them back to NY and had the necklace made. The clasp is silver. Necklace is in excellent condition. I may have worn it up to 4 times in the past 8 years otherwise being kept in the safe. Looking for its new home. Sorry I can’t quite remember what the exact stones are of hand.
