I assume this post was intended for the OP, however just for clarity - the Crystal Guide development team are not involved in any sales or authentication of minerals or sellers on these forums. While we permit private sales posts, they are unverified third party (user-to-user) offerings which are not overseen or affliated with us in any way. Potential buyers/sellers are therefore strongly advised to perform their own due dilligence before exchanging any personal information or entering in to any transactions with other users. All users transact entirely at their own risk.
