Tantalite with quartz
description: <p style="text-align: justify;">LOCALITY:  Northern Areas, Pakistan </p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">3" across <br /><br />Ferrocolumbite is a rare tantalum containing mineral that rarely occurs in pegmatites. Esthetic examples of this species are very rare. This piece is distinguished by the following list of desirable traits: <br /><br />(a) The ferrocolumbite crystal is lustrous. <br /><br />(b) The ferrocolumbite crystal is pristine on its edges and vertices. <br /><br />(c) The ferrocolumbite crystal is placed in the middle of a well proportioned matrix. This contributes to the esthetically pleasing composition of this piece. <br /><br />(d) The color contrast between the snow white matrix and the lustrous black ferrocolumbite crystal is stark <br />and esthetically pleasing. <br /><br />(e) The quartz crystal (also sharp, lustrous, gemmy and generally esthetic) is positioned next to the crystal of ferrocolumbite. The combination of these two species is esthetically pleasing. <br /><br />All of the above traits make this specimen an elite example of this highly sought after rare species.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">Now in the collection of Professor Stephen Smale  </p>
