Precious Chalcedony Flowers with tiny crystals that give it an excellent shine.

Chalcedony, traditionally considered a variety of quartz, more recently it has been seen that it is actually a mixture of quartz with moganite, a mineral with the same chemical formula but monoclinic, the mixture producing the typical banding of some varieties of chalcedony.

Chalcedony Flowers form very slowly, they have a flattened shape as they usually form in the long fissures of basaltic formations. They have a spherical nodule, from which extend rough surfaces of a beautiful bluish-grey. These rough surfaces can be flat or raised in the shape of a bowl, forming the flowers.

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.
