Hello my name is Glenda, .Please note I am unable to do live phone conversations. I will not send a message to you asking for a phone call. If you get a message asking to do a phone call, this is not from me. It is an automated message from elsewhere. ...I have been in the antique business for over 45 years, Appraising, Antique shop owner, also buying and selling on today's current market. it is my pleasure to put my experience to work for you. .
Can you send a picture of the back of this?
I am unable to find any rock that looks like the rock you have. The best thing for you to do is to take this to an appraiser in your area so they can look at this close up to determine just what this is and what the value is. They may also recommend you have this tested for age. I can find you a list of appraisers in your area if you like, some you can call.
