ID: CC21651
The rare mineral Tapiolite is a tantalum niobate with the presence of iron and manganese.  Two distinct species are officially recognised, Tapiolite-(Fe) and Tapiolite-(Mn) which form a continuous series, somewhere in which this specimen lies.  Analysis would determine its exact species.  From the Baixão da Laje mine at Parelhas in Rio Grande do Norte, Brazil, this partial crystal is a fine ex. matrix example and on initial glance looks like a good sized Cassiterite crystal, save for small areas of iridescent colours.  It is entirely black and both the crystal faces and semi-conchoidally fractured surfaces have a highly reflective metallic lustre.
