This silver Turkoman or Kazak fibula (breastplate) measures approximately nine inches from top to bottom. The diamond shape measures about five inches side to side or 4 1/2 inches when measured straight across as a square. It is about 1/4 inch or 6-7 mm in thickness. It appears to be solid rather than hollow. It has a black linen pad hand stitched to the reverse , which helps to document that it was actually a family heirloom, rather than merely having been produced to sell to tourists. It dates from the latter part of the 19th century and is in excellent condition. It is inset with carnelian, jade and black onyx or jet cabachons. It is covered on the front with gilding and triangular silver shapes covered with silver dots. It is unmarked, but guaranteed to be about .900 silver or better. Many silversmiths melted old silver coins to obtain their silver for making jewelry. Most coins were about .900 silver in quality.
