Ben - it is actually more valuable than emerald because it is a good deal rarer, as Mt. St. Helens is the only place it can be found. I have been fortunate to cut 1 in my life so far and I was sweating bullets the whole time I was working on it. A 26 carat rough stone yielded a beautiful 12 carat cushion cut stone. Value on cut stone was $3,500.00.
