This vintage Mexican silver necklace is a book piece on page 15 of the book by Morril and Berk, MEXICAN SILVER. Both, the piece in the book and this piece are hallmarked with the same 980 TAXCO dating both to pre-1948. This link originated by William Spratling. The weight is 74 grams heavy and is one inch tall. The length is a comfortable 17.5in. long. The piece is free of dents but there is glare that can be confused as a dent. The visual effect of this piece is rich and gorgeous with ANYTHING! Fabulous on, just LOOK AT THAT NECKLACE!
