1/20: The outer layer of gold is at least 1/20th (5%) of the piece's total weight. 
12k: The purity of the gold plating layer. 12-karat gold means the alloy is 50% pure gold.
G.F.:  Gold Filled. Unlike standard gold plating, which is microscopic and rubs off easily. Gold-filled jewelry is made by bonding a thick sheet of solid karat gold to a core metal using intense heat and pressure. It is highly durable and a signature characteristic of quality vintage jewelry.
 "On silver" (The Base Metal): The underlying core metal beneath the gold jacket is solid sterling silver. It shows a heavy, warm patina, natural silver tarnishing that comes through the gold layer over time. 
"A & Z" (The Manufacturer) is the official maker's mark for the A&Z Chain Company, a highly regarded American jewelry manufacturer founded in February 1905 in Providence, Rhode Island. See less
