Vintage Signed C.A.B. Zuni Native American shop Thunderbird Pin Turquoise/MOP Inlay

Product Name: Vintage Signed C.A.B. Zuni Native American shop Thunderbird Pin Turquoise/MOP Inlay
*can be worn as a brooch or a pendant *Sterling silver with inlaid stones (turquoise, mother of pearl, shop other) *Overall all good condition with very little wear EXCEPT there are 2 small cracks in the very bottom teardrop turquoise stone (see photo). The photos make it look like the very top of the MOP head is cracked, but when looking at it with the naked eye there is no visible crack/damage. What I am seeing in the photos appears to just be where the silver meets the stone. *There is a strong patina (I leave the polishing to the buyer) *Pin/clasp works well *2.0" x 1.7" (approximately) *The back is engraved "C.A.B" and "Zuni" *Weighs about 11 grams.
