Raw natural Hawk's Eye in which its beautiful grayish blue stripes can be appreciated.
Hawk's eye is a blue-gray variety of tiger's eye. It is a variety of quartz that presents the "chatoyance" effect, vertical bands with reflections reminiscent of a cat's eye. This effect is produced by the orientation of the fibrous inclusions of crocidolite it contains.
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 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.
