Black Stones
are also known as Black Jaspers. They are found in
crypto-crystalline opaque form. From their name, it is clear that
they are found in black or deep brown color. Beads made out of these
stones have little economical value and therefore, mostly used for
inexpensive jewelry and other house hold and small ornamental
objects. These are found everywhere and specially in the clay. It is
believed that these stones have the ability to absorb the negative
power. These stones are also considered as good for protective
purposes, and specially for women during the birth time of their
child.
