I know some of you are a bit puzzled by this stone. So I’m going to be kind and give you a hint (or two, or three). If you’ve already entered the giveaway you have until Monday to re-enter (I’ll delete your first entry.)
Hint 1: This stone came from England.
Hint 2: Check this forum thread, not for the name I’m looking for, but for some excellent keywords to use in a Google Search.
Hint 3: It has it’s own Wikipedia page. 😉
