Tan Agate, a variety of Chalcedony. Or Jasper And sterling Silver Pendant 9.8 grams 2” Acid tested for sterling silver I have had all the pendants listed for over 10 years. They do need to be cleaned. Some I clearly remember the names and some I may be off. They are gently used and may have a ding or two from being tossed around in storage.
