Its pretty easy to tell flame fusion material from hydrothermal in the rough. This photo shows two flame fusion sapphires on the left, and hydrothermal blue sapphire slab and emerald hydrothermal slab.

The difference in price is dramatic. The two flame fusion boules were less than $25, both hydrothermal pieces were over $1000.
