There, the unlikely combination of several geological factors made possible the occurrence of a wide variety of finely crystallized mineral species, to such and extent that this deposit set the highest international standards for several species over the second half of the last century. Among these, wulfenite is among the greatest classics, as Tsumeb is ranked among the most iconic localities for the species! Here is a representative wulfenite specimen from the deposit displaying caramel brown colour tabular crystals in combination with micro smithsonite and some white quartz. Ex collection Lefebvre. Jean-Claude Lefebvre was born on May 8, 1942, in Liège. A graduate in geography, he began his career as a teacher before becoming a high school principal. A man of wide-ranging interests, he was passionate about astronomy, travel, and numismatics—as well as mineralogy, to which he devoted over thirty years, building his collection between 1980 and 2010. His approach was that of a rigorous and deeply committed autodidact. He initially developed his collection horizontally, aiming to represent as many mineral species as possible, more than 380 in total. He then refined it vertically, focusing on aesthetics, specimen integrity, and overall balance. He possessed a keen eye, that rare ability to instantly recognize the right piece, one that required no compromise. Among the highlights of his collection are an outstanding group of specimens from the Congo, along with a remarkable suite from Mont Saint-Hilaire, Canada, a legendary locality renowned for its rare species and complex crystal formations.
