This superb lozenge-shaped breast plate or pectoral is from the Tekke (Teke) people of Turkmenistan and Afghanistan. It comprises a finely pierced silver sheet with applied pearled silver bands, five oval-shaped carnelian-type stones in box settings, and fire-gilding (gold plating.)
Suspended from the lower edge of the pectoral are 29 silver chains each of which terminates with a silver pendant. These are embossed with grooved patterning and might represent highly stylised fish.
It is suspended from a fine silver chain necklace.
The reverse is of unadorned silver.
Similar examples are illustrated in Hoek (2004, p. 97), Kalter (1984, p. 119), Seiwert (2009, p. 253), and Borel (1994, p. 124).
The example here is in excellent condition. It is wearable and stable.
