Peruvian black jade (also called Lemurian jade) is mined within the area of the capital Lima. It is a soft porous stone.

Because of its internal structure the polish never gets to the shine one is used to from other black stones like obsidian but rather stays a little more dull. We at Gemrock Peru, however, have developed a technique of dry polishing that provides the best possible polish on this stone.

Peruvian black jade comes many times with tiny pyrite sparkles or fine pyrite lines included, which is a good way to identify the rock.
