Product Description
Trona is a fairly common sodium carbonate mineral, chemical composition Na3H(CO3)2·2H2O, which is only infrequently found as a faceted gem due to its softness, 2.5 on Moh's scale, and that it is soluble in water.
It forms as relatively small crystal crusts on the walls of caves as a non-marine evaporate mineral, this translucent, banded example coming from Searles Lake, San Bernadino county, California, USA.
