Hi Anya,
I'm sorry you did not find the bead as described. I do my best to show the size of the bead, even including a photograph in the listing that shows a closeup of the bead next to a quarter. Most people want more shungite versus less, and the smaller the bead (or the smaller any shungite piece), the less protective.
If you wish to return it, please contact me via email, val@shungitequeen.com. Thank you!
