A thin dusting of Tyuyamunite rests in a hollow in the base rock of this piece. The Tyuyamunite may occur in a crystalline form, but if so, the crystals are far too small to be seen even with a loupe. It essentially occurs as a dust that coats a calcite druse. It has the standard bright yellow coloration and is dull in luster. The calcites are generally extremely warped so that often one cannot see any definable crystal form. The host material appears to be made out of limestone.
