As I sorted through numerous volumes on antique jewelry, I came across a photograph of this unusual Scottish brooch. It appears in Diana Scarisbricks' book SCOTTISH JE WELRY: A Victorian Passion on page 93. Her description is as follows " An open square set on its point comprised of four small diamond shapes set with diamond-cut stones set between four round cabochon stones centered on a cairngorm.
Splendid stone gutting and a variety of various types of local agates of several types made it possible to create jewels with a special charm that is a part of the legend of Scottish jewelry.
It measures 1 and 5/8 inch by 1 and 5/8 inch and is set in unmarked sterling silver. The steel pin and silver clasp are original. The condition is excellent.
