Ivan V sterling silver turquoise big boy watch cuf

It's a Navajo sterling silver/turquoise big boy watch cuff. I had it authenticated by a jeweler at Jackson's Jeweler. The jeweler confirmed that it is .925 grade silver and the turquoise is also authentic. It weighs 111.68 grams and is made by the artist Ivan V who makes countless other pieces. The jeweler appraised this piece between $300.00 - $500.00, due to the market for this type of jewelry.
