columbite (var. manganoan ferro columbite)

Western Australia - Black in the Outback

These Niobium and Tantalum Oxide specimens are some of the largest & have the most well formed crystal terminations and forms known in the world such as singly terminated prisms with square to rectangular cross-sections. The prism faces are small and the pyramid faces large  They are from an Archean aged (2,665 million years) Pegmatite intrusion within an ultramafic peridotite located in the Yilgarn Province.  The black Iridescent metallic luster of the orthorhombic columbite crystal faces on a Feldspar/Quartz Matrix provide a striking contrast in colors.   These are from a Published World Class Locality and recent mining has uncovered new specimens.  Mass Spectrometer analyses indicate that the columbite contains significant quantities of Iron, Manganese, Magnesium, Tungsten, Titanium, Vanadium, Tellurium & Zircon in addition to the Niobium and TantaliumAccessory Minerals in the pegmatite Include Quartz, Albite, Microcline, green Beryl, red Garnets, Muscovite & Tourmaline (var. Schorl).

Crystal size: up to 22 x 11x 8 mm, and 15 x 16 x 7 mm (0.89 x 0.45 x 0.32) Specimen size: 86 x 54 x 62 mm (3.25 x 2.14 x 2.45) Weight: 355 g

One of the only specimens recovered as a crystal group. Specimen consists of five main crystals, with two smaller crystals growing from a white clevelandite-type albite matrix. Crystals are sharp, vary from simple to complex terminations and have a good lustre.

C2 ferro columbite, Giles Prospect, Spargoville, Western Australia

Crystal size: 61 x 30 x 19mm (2.40 x 1.19 x 0.76) Specimen (approx): 75 x 62 x 69 mm (3 x 2.46 x 2.72)

Complex terminations or parallel growth of crystals has resulted in this large specimen. Faces are lustrous and exhibit an iridescent patina where faces contacted quartz. This is characteristic of columbite from Spargoville recovered from certain zones within the pegmatite. Damage is present on the terminations (visible in photos) and the specimen is repaired. The lower price reflects this.
