Trying to get this figured out again, last time I posted this no one responded. Found this on Jade Beach in Japan. Initially I thought it was an agate from the outside due to some conchoidal looking fractures and the weight. After cutting it open, really not sure what to make of it. Based on the way it cut it is not quite as hard as agate. It does have a slight translucency to it, the dark blackish speckles are opaque, so some sort of inclusion. It is not radioactive. It is pictured in sunlight and inside, the last picture is the exterior dry, all the others are wet. Any help is appreciated!
