Hi, If you have the tools-you can measure Specific Gravity to rule out certain minerals.

For instance Specific Gravity of Hematite = 5.3 Grams/cc
Specific Gravity of Schorl (Black tourmaline) = 3.15 gm/cc.
Specific Gravity of Onyx = 2.70 gm/cc

We just used this test and it works!

Good Luck and please let us know!

P.S. This technique works for minerals of Uniform composition- not Mixes or conglomerates
