Like new artisan made obsidian, malachite, and silver collar necklace

In like new condition. Only worn twice. Purchased from a local couple a year ago - it was from their jewelry store they had just closed. Artisan made with black obsidian, malachite, and silver. Secure clasp. Short collar fit necklace. Absolutely beautiful piece. I love this but I'm moving abroad and need to drastically downsize.
