Victorian Scottish Agate Sterling Silver Horseshoe Brooch. Wonderful Victorian Scottish agate horseshoe brooch/pendant made between the 1850s and 1880s when Scottish agate jewelry was in favor due to Queen Victoria's love of it. The buckle on the front denotes a "forever relationship" and is made of sterling (acid tested). It is typical of much jewelry of that period in that it is not marked. It is quite large at 2 7/8 inches long by 2 1/8 inches wide. The brooch is inlaid with green, red, and other colors of agate or jasper. The back closes securely with its original c-clasp. The back has a clip to hold it to a garment and a ring so it may be worn on a chain as well as fastened. The engraving on the sterling is both delicate and beautiful. In original condition as the agates never quite fit their silver frames. A great old brooch to wear today. A collectible.
