Rock Hounds looking for stones in Jamaica

We like exploring and finding semi precious stones, here in california we have places we go to and mine for stones - anyone know if there is anything like that in Jamaica? Near CSS? any tour or the like that we can go and explore and collect stones. any mines that allow guests to sift through the dirt after it comes out? Hope someone knows something about this type of adventure in Jamaica. thanks for all the great threads on here - what a great way to get an idea of what to expect when you arrive.

You may want to pose this question on the Negril Form on TripAdvisor. There are a lot of very knowledgeable ppl on that site who might be able to give you some info....
