Wonderful Scots agate brooch in a geometric inlay pattern with bands of white, bloodstone, black onyx, jasper, moss agate, and mossy jasper. The agates are bezel set with a twisted wire border and an older C clasp. The metal is unmarked, but I believe it is sterling.
The back has a tag marked "circa 1910" which was there when I bought this piece. Brooch measure 3 x 3/4" x 1/4" deep and is in excellent condition. Nice addition to a collection of Scottish jewelry.
