Small crystals of red Quartz or Jacinto de Compostela, some of them doubly terminated.
It receives this name because the pilgrims carried it when they made the Camino de Santiago.
The Jacinto de Compostela is a variety of phanerocrystalline quartz. Its reddish orange color is due to the presence of iron. It is also called red quartz or hematoid quartz (contains hematite).
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.
