Massive high-quality Amethyst with a transparent violet color typical of the mineral.
Amethyst is a violet macrocrystalline variety of quartz. The color can be more or less intense, depending on the amount of iron it contains. It can appear colored by zones with transparent or yellow quartz (citrine).
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.
