Deep dark blue crystallized azurite.
Like all copper minerals, azurite is toxic, but it can be handled with your bare hands. In ancient times, azurite was ground to use as a blue pigment.
Azurite is also considered a copper ore because it reveals the presence of other ores by being associated with them.
The mineral includes a label with the name and origin and is attached to a cardboard box. 4 cm square.
*The price is per unit (a single cardboard box of the four shown in the photo)
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.
