Dioptase crystallized on a green matrix typical of the mineral.
Dioptase is popular with collectors, occasionally it can be cut into gems that are similar in color to emeralds.
At an industrial level, it can be used as a ground pigment in the preparation of paint. However, this application is not usual.
The mineral includes a label with the name and origin and is attached to a 4 cm square cardboard box.
*The price is per unit (a single cardboard box of the four shown in the image)
Since the minerals are natural, you will receive a piece similar to the one in the photograph. The minerals come in cardboard boxes and are glued to a porex base with hot silicone; these can be removed using ethyl alcohol without damaging the mineral. The size is approximate.
