Silver/Gold/Diamond Statement Pendant Necklace

Custom-made necklace - similar style to David Yurman (but it's NOT a David Yurman). Made of 1925 silver with 14K gold trim, with single cut diamonds in the center of the square pendant. Overall length is right at 17 inches. Sorry I don't know the total karat weight of diamonds. I purchased new from the jewelry store and haven't worn it very much, so it's in excellent condition.
