Massive white Adularia. In some specimens, iridescent tones can be seen on its surface, called adularescence.
The mineral nepheline is a rock former that is present in igneous rocks with low silica content. Its occurrence occurs as a glassy crystal in some recent lavas.
These specimens from Morocco are usually associated with "Melanite" black garnet.
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.
