A mesmerizing Gibbsite and Azurite combo piece from the January 2021 small find discovered in the Yangwan Cu deposit in Wenshan Mine, China. This is by far the best Gibbsite we’ve seen from China in terms of colors and mineralization. The piece displays an eye-catching myriad of botryoidal Gibbsite aggregates in a vivid sky blue color, some of them have interlinked to form into a rare stalatitic shape which is super rare and beautiful! Some highly crystalized Azurite crystals have grown over a surface of Goethite on the back of the specimen, adding uniqueness and aesthetics, incredible! Comes with a high quality acrylic display box.
The vein-type and stratified Copper deposit of the Yangwan ore field in Malipo County, Yunnan is one of the few mineral deposits in the world which was formed during Middle Triassic (about 247 million to 235 million years ago). It is located in the eastern part of the famous Wenshan Prefecture (Wenshan Mine) where world class blue Hemimorphite and Gibbsite specimens are found.
