This turquoise, onyx and opal inlaid pendant is Navajo made and hallmarked Fransisco. There are several artists with the last name Fransisco but I have not seen this hallmark before so I am not positive about which one it is. It is sterling silver and measures 1" from the top of the bail by 1/2" wide. This pendant comes with the chain pictured which is a 1.5 mm round box chain available in 16, 18 or 20". We will default to 18", if you would like a different length please leave a message with your order.5% of the profits from this item will be donated to the Native American Rights Fund.
