Item Description

A 1.4 cm, sharp, metallic lustre, tetragonal Tapiolite-(Fe) crystal with eyecatching light iridescence is aesthetically set on the matrix plate of flashy pearlescent muscovite plates and quartz. Tapiolites are uncommon Fe and Mn Ta-Nb oxides found in pegmatites. This obscure pegmatite in Paraiba State has recently produced some outstanding specimens of Tapiolite-(Fe) and this is a very fine example.
