I'm not the best with prices either. There is one similar to yours for 2000 pebbles, and another for 3000. That seems to be the range. Does that sound fair? I have moonstones too.
I only have 2 right now. Were you looking for more or less that that? Being as I am mainly finding 2000-3000 pebble puppies like yours and 1 moonstone is worth 10000 pebbles, what do you think is fair?
