Item Description

A richly colored and visually appealing specimen of cobalt-bearing Dolomite from the Katanga Copper Crescent in DR Congo. Cobalt is a powerful chromophore, creating some of the most vivid hues in the mineral world, especially in certain carbonate species. This piece is a beautiful crystallized "mound" featuring a coverage of vivid purplish-pink, translucent crystal aggregates on matrix. No major damage on the top/display side of the piece, and that color just GLOWS when the piece is backlit. Priced at $1,000 in the inventory. From the collection of Vasco Trancoso, a medical doctor and prominent mineral collector from near Lisbon, Portugal (https://www.mindat.org/user-11954.html). He assembled his mineral collection over the course of 60 years, and built a fine worldwide display collection that we recently purchased. This piece is pictured on mindat.org at https://www.mindat.org/photo-1208607.html
