Wow, this is an incredible story about an Emerald mine in North Carolina, USA, and what has recently been found there:

I'll bet that owner takes over exploring the rest of that mine himself after these large, and very profitable, discoveries have been found.
Also, I wonder if there are any other US states where jewels like this are mined or have been found. I guess I always think about diamonds and other stones/jewels being found in places outside the USA rather than inside the country.
