Colorado law says age is dependent on the parents, as for that particular piercing, the piercer would need to see her ear. Hopefully you find this helpful and feel free to come the shop. Owner's response.
16 with ID and parent, if I remember correctly
I'm not sure about this shop, but most places won't do it unless she's at least 16. You should call to make sure you bring the right documents to prove her age and that your her parent.
