Neil, can you give us some details, about where found. Not asking for GPS coordinates, mind you, but rather hints at geographic information to allow a better chance at identification. So, if this was found outside a silver mine in or around Flagstaff, Arizona, it would give us a starting place to refine our guesses.
This stone, maybe emerald.

Dear Weasel, thanks for responding to all three questions, most helpful thank you. I'm posting these images on behalf of somebody else, however, I understand that there are Emerald's, Silver and Copper mined within the region. Does this help? Also 4 lbs of Emerald sound potentially valuable! if this mineral does prove to be an Emerald, could you estimate its potential value? And if they wish to sell these three specimens, could you please recommend how they may proceed. I also forgot to mention that all three minerals scratch toughened glass. Thanks again for your assistance. BR Neil
If in the US I would guess North Carolina. The emerald would be most valuable but there are so many variables. Inclusions, clarity, useable karats after cutting. A start would be taking the stones to a lapidary. That is a guy who can get you started. He will be able to clean, estimate karat weight and cut your stone. He may even wish to purchase them. Lapidaries work for jewelers and rock shops. I would say, starting there or perhaps a rock club whose members will know reputable dealers and lapidaries in your area. Be diligent, get at least three appraisals. There is no way to estimate worth. They have ways to see exactly how much of the stone is useful for cutting into gem quality stone. Inclusions are impurities captured in gem stones and they affect value, karat weight of useable stone, color... good luck. There are websites which give current value for gems by weight and quality and it is usually given as a range. That is because of the things already mentioned.
Dear Weasel, thanks once again for your supportive advice. I'm not familiar with Lapidaries so I will naturally follow-up this lead. If I may ask another question, as the mineral may potential have some significant value, how does one manage the ownership issue? If this mineral is handed over to someone else, how does one maintain title over the mineral, especially as it was just picked up off the ground? In these circumstances, if one picks up a mineral, do they automatically gain the right of ownership, or are there other factors that one needs to take into consideration?  In your opinion, do I need to organise something first before I contact Lapidaries? Thanks again, BR Neil
Reply, talk to a lawyer as laws are different everywhere. In many states you may not own what's on your own land. There are mineral rights, water rights and property rights. A lawyer can properly advise you. Most people are honest, some are not scrupulous.. Taking a witness and filming it with a phone will keep most people from just taking it. In North Carolina, the largest emerald found was in someone's back yard, he'd been collecting for years, he knew the applicable laws. Here in my state a man found an exceptionally large fossil stone and the state has a law where it owns every rock over twenty five pounds. The state seized it from him. I have a 200 lb. puddingstone they could seize even though I found it on my property, dropped here by a glacier. Don't tell anyone, find out what rights you have, where you stand legally and go from there. You could actually purchase the mineral rights to a property and search for more stuff. Samples like that could be worth mucho dinero.That is what I would do. Seek the mineral rights and do what is right. I want to leave you with the understanding, I am in no way giving you legal advice, I am not a legal professional and advising you to seek legal advice is the wisest course I could give you.
Dear Weasel, thanks once again for some excellent advice, I will pass over your suggestions and keep you posted with developments. I was curious to know, if one passes over their mineral to a lapidary, how does one know that, what is returned constitutes the whole mineral? As no doubt, what will return will constitute multiple individual gems? I recall Archimedes faced with a similar challenge before his eureka moment! Are there protocols in place or methodologies to address these concerns? Thanks once again for your assistance BR Neil
