Stephen Dweck Beaded Y Drop Toggle Necklace, SS

Fabulous and Fun Stephen Dweck Beaded Necklace. This piece is bold with round beads connected by oxidized sterling silver circles. The beads are in various shades of orange, green, yellow. I think they may be tourmalines but not 100% positive. The beads end with a large sterling toggle closure. Then there is a drop that has various sized sterling circles with one circle a pale green stone. At the bottom is a sandy brown stone in a tear drop. I am not sure what the stone is. The Beaded necklace is 20" and the drop is about 4 1/4 inches. I have never seen another Dweck piece like this, could be a 1 of a kind. The toggle is stamped 925 Stephen Dweck. This is in excellent pre-owned condition.
