I don't know what this is or where it was found, but the seller called it "prairie agate." But, this may be a generic name or a wild guess. It has some depth to it and looks like poppy seeds tightly packed together. The pendant measures 1-1/4" by 3/4", for scale. Does anyone know for sure what this is?

free4mns: Most of those kinds of agate go under common names like oolite if the orbs are tiny, or pisolite ( resembling fish eggs) if the orbs are larger. Sometimes it's also called "rice agate" if the orbs are oblong. Some of the oblong forms are fossil in nature being fossil Fusulina sp. , a type of hard shelled foraminiferan protozoan. There are also of course, conglomerates, formed of various sized pebbles cemented by chalcedony. The orbs in your example look to me to be a bit irregular in size but this can be caused by the actual sawcut which bisects the foraminiferans at different parts of the shells and in different directions depending on how they lay in the piece. As my best guess, I'd classify it as the "Rice Agate" of fossil origin. There are many fossil type agates in the region where prairie agate comes from too....mel
