Aggregates of metatyuyamunite crystals, with an intense yellow to orange colour, accompanied by malachite radial agregates and yellow laminar carnotite.

Group of very well defined cuprite crystals showing very unusual facets both for the species and for this classic locality for the species. They have very well defined faces of the cube and the octahedron, together with those of the dodecahedron. Under intense light the red transparency is observed, but the surface shows a gray patina, the years have passed away. They are placed on a cavity of brilliant calcite crystals. An interesting rarity.

These cuprite crystals from Kolwezi mines are a classic of worldwide mineralogy. In this specimen the crystal shows defined faces and edges, with intense red color under the light. It is disposed in a cavity with needle malachite crystal aggregates. Crystal has no damage, the back side shows natural rounded forms. A very aesthetic and difficult to see specimen.

On a compact quartz matrix we have different groups of cobaltoan calcite crystals with intense purple to fuchsia color, with transparence and well defined faces and edges. It is accompanied by spherical aggregates of snowy white dolomite and some quartz crystals. A classic from Katanga Copper Crescent mines.

This specimen shows spherical aggregates of plancheite, formed by several acicular crystals in a radiated shape. On the surface of the spheres we can enjoy curious honeycomb structures. Color is between blue and blue-gray. On a vug layered by small quartz crystals. From a locality not well represented in collections for this species.
