925 sterling silver necklace by designer Mimi & Marge, handmade, medieval

Vintage sterling silver necklace by a well known designer Mimi & Marge. Handmade in ancient medieval style, with Celtic elements. In excellent condition. Stamped 925 on the clasp and on the adjacent plate. 16" long chain, 2" long pendant. The pendant isn't stamped (or it is hard to find it), but I am assuming it is sterling silver as well.
