Merlinite

Merlinite is the Druzy form of the mineral Psilomelane. It is black with
silvery banding. The thousands of tiny crystal which cover its surface in the
druzy form give it the appearance of a black midnite sky filled with starlight.

Merlinite is a seer's stone, for viewing past lives or future potentials. It
resonates with Lunar cycles, and is best used for New Moon scrying, but it is recharged by the Sun.

Merlinite also has a strong connection to Earth Magic – use it to contact
with the Elements, and one's own inner power and magic
