Up for your consideration is this Vintage Scottish Sterling Silver Dirk Brooch by renowned jeweler J. Cook & Sons. It has a yellow citrine in the handle of the dagger and pale blue and tan agate on the shaft. All the stones are in excellent condition with no cracks or grazing. The underside is Hallmarked, which is relatively rare for these pins with "J.C.& S."For J. Cook & Sons, the Anchor for Birmingham, and the lion standard mark along with the letter "P" dating the brooch to 1915. Pin back has a simple hook clasp. Measurements: 1-3/4" x 1/4". Absolutely gorgeous little brooch; it would make a wonderful child's kilt pin.
