Majorica Pearl Necklace on Dark Brown Leather Necklace

Brand new, never worn necklace from Majorica. It’s absolutely beautiful. Three movable pearls with thin dark brown leather “chain” - each pearl has a knot next to it to prevent it from moving too far. I believe the leather portion is adjustable to different sizes but I’m not sure how to do that. Purchased overseas and I found I haven’t worn it, so I would love to find this unique piece a new home. Comes with box and authenticity card.
