This natural Gray Chalcedony has not been treated to enhance color or clarity in any way.
The term chalcedony refers to many cryptocrystalline quartz minerals, including agate, jasper, chrysoprase, and onyx. The term cryptocrystalline lends to a rock texture so subtle that the crystals within cannot be seen with a standard microscope.
