Carrollite on calcite with chalcopyrite
description: <p style="text-align: justify;">LOCALITY: Kamoya South Mine, near Kambove, Katanga Province, Democratic Republic of the Congo <br /><br />1 9/16" Across <br /><br />A strength of this piece is the completeness and freedom from damage of the carrollite crystal. Unfortunately, the carrollite crystal is only small with a moderate luster. The carrollite crystal is also partly embedded in the white calcite matrix. This piece would be far more desirable to most private collectors if the carrollite crystal was less embedded. This trait would be far more desirable since it allows the crystal gazer to more readily appreciate the geometry of the carrollite crystal. <br /><br />The author imported this piece into Melbourne, Victoria, Australia after three weeks spent buying Katanga mineral specimens in Lubumbashi and Kolwezi in late 2009. The author imported hundreds of carrollite specimens that ranged from inexpensive reference specimens like this piece to elite carrollite specimens like the outstanding isolated carrollite crystal on a well proportioned calcite matrix featured on this Webb-site. This piece is worth around AU$40 at retail including postage anywhere in Australia. The author supplies reference, teaching grade or "stock minerals" at very competitive prices. This is because the author primarily works only with much higher value mineral specimens. Despite this, the author also acquires a continual stream of inexpensive mineral specimens that are often sold below cost price. This is of course compensated by the appreciation and greater liquidity of elite mineral specimens that the author also encourages all collectors to strive to collect. <br /><br />Photo by Matthew Webb of Melbourne, Victoria, Australia</p>
