What little is not too expensive tends to be old stock. There remains a fairly good supply of cut goods on the market, although large stones in general do not seem to be selling well for some reason. Perhaps it has to do with the economy and stock market. Large stones are often looked at as hedges against inflation and portable wealth. In times of good economy and low inflation, people don't look to these interests.
Demand is still good, but mostly for small stones.
Rough is still very scarce in smaller sizes, with most goods being supplied from Africa or Germany or Sri Lanka cutters. Larger rough is available in America, but at high prices, certainly not worth hacking up into smaller stones. What smaller rough is available here is overpriced to the point that it's hard to make a profit. And larger stones aren't selling that well. There is some question as to the actual source of the tourmaline nodules on the market that supposedly were coming from Mozambique.
