Very interesting novelty of 2007 Munich Show: trigonal crystals of Ilmenite transformed into an intimate intergrowth of Rutile and Hematite. Microscopic examination shows that Rutile (reddish) occurs as a delicate network of needles which are oriented parallel to the basal sections of the former Ilmenite, while Hematite (black) forms the interstices.
If you want to know more about Rutile and Hematite pseudomorph after Ilmenite please follow this link
Between 2001 and 2003 Congo has given us fabulous Carrollites, which were much better than the older ones. We got hold of many nice specimens that sold well on our web pages. We still run into them when buying from our normal sources and we still see some good specimens which we can offer on our website. Thus we can continue to offer this excellent mineralogical species.

From the great Poldervaartite find made in South Africa we offer this further material. The quality is, as you can see, much better than the old ones found in the Wessels Mine. Notably the color is much more intense and redder. On the subject of the color it is necessary to warn you that some of these new Poldervaartites show an intense color change depending of the kind of light used: in day light they become yellowish but in artificial light they are a spectacular strawberry red color.
