Massive Chrysoprase of intense color in extra quality.
Chrysoprase is a variety of quartz that owes its greenish color to the fact that it contains small amounts of nickel. It is generally light green in color, but can vary to dark green.
It is considered a hard stone and is used as a gem and for the manufacture of ornamental objects.
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.
