I want to say thank you I’m advance for any help. I found this well detailed stone frog. I’m not sure what it’s made of either type of granite or stone. Has some lettering around edge of the rock that the frog is sitting on. It’s so faded cannot make out much just letters a and n. But I’m bottom has a faint impressed mark that resembles a seal with faint eitherchinese or Japanese marks. I cannot get pictures as they are worn so bad. Reason I noticed it had the frog tilted where I noticed the mark. Weighs almost 3 pounds. Size is around 5x6 inches. I’m just hoping someone can shed some light on it. Age, who possibly could have made it and where it may have been made? Basically any help on it.
