- The natural often shows a magnetic response to a rare-earth magnet (think N52). - Malachite is quite dense. If you have the means to do so accurately, a SG test should throw up anything containing a substantial amount of resin or glass. Anything outside of the range 3.25-4.01 has to have a reason why.

Malachite: The mineral malachite information .
Malachite is a popular mineral with its intense green color and beautiful banded masses. The banded specimens are formed by massive, botryoidal, reniform, and especially stalactitic Malachite that are dense intergrowths of tiny, fibrous needles. Dense banded specimens are often sliced and polished to bring out their beautiful coloring.
