This is hallmarked Mexico Sterling and with Fred Davis's eagle 22. This piece was made at the same maker as this design with the FD Hallmark and is identical in every way to those pieces. It has a wearable length of 16 inches and the link is 7/8in. wide. The caviar amethyst sit majestically on top of a "teat". The silver is silky to the touch. Perfect condition and weighs 80 grams. Absolutely lovely, LOOK AT THAT NECKLACE!
