Jet is one of the organic gems. It is fossilized wood, millions of years old.
Jet is typically black in color. Care must be taken when purchasing Jet because
plastics, glass, and vulcanized rubber are sometimes marketed as Jet. Purchase
Jet only from reputable dealer. Jet shares with Amber the property of
gaining an electrical charge when rubbed with silk or wool.

In ancient times it was called black amber and was honored for its mystical protective uses.

Jet should never be exchanged from one person to another as it has a
direct link to your soul. Consider it a one person stone. If you wish to purchase
antique Jet be sure to cleanse thoroughly before wearing it yourself.

Jet is the Knight-errant of the mineral clan, protecting the defenseless
and weak and exerting his energies for justice and goodness. Use it as a
personal protection stone while traveling – either worn or carried in pocket.

Jet is helpful during times of transition as he facilitates acceptance of
change and encourages growth, inner development and self-improvement.

Astrological sign Capricorn. Base Chakra.

Jet has a hardness of only 2½ to 4, which makes it a little soft to wear
as a ring stone, but fine for beads and other jewelry.
