"The Volcano"
Item No. 2007-010
A 1.75-inch shield-shaped pendant of mahogany obsidian, wrapped in 14k gold-filled wire and set on a chain of jet (black onyx) and hematite beads of various shapes, offset with vermeil (gold-filled) spacer beads.
OBSIDIAN (SiO2) Silicon dioxide.
Obsidian is volcanic glass...molten silicon cooled with a variety of minerals that provide color. The brilliant orange in mahogany obsidian results from iron mixed with the silicon.
Pure obsidian is usually dark in appearance, but the color varies depending on the presence of impurities. Iron and magnesium typically give the obsidian a dark green to brown to black color. A very few samples are nearly clear. In some stones, the inclusion of small, white, radially clustered crystals of cristobalite in the black glass produce a blotchy or snowflake pattern (snowflake obsidian). It may contain patterns of gas bubbles remaining from the lava flow, aligned along layers created as the molten rock was flowing before being cooled. These bubbles can produce interesting effects such as a golden (sheen obsidian) or rainbow sheen (rainbow obsidian). Obsidian is relatively soft.
The obsidian in this pendant comes from lava fields in eastern Oregon.
HEMATITE (Fe2O3) Iron oxide.
Hematite is a silvery, shiny opaque stone that almost looks like metal. Hematite is heavy and relatively hard oxide mineral, that constitutes the most important iron ore because of its high iron content (70 percent) and its abundance. Ancient Egyptians used hematites as ornamental objects placed inside their tombs. Red ochre was used by prehistoric artists in their cave paintings. Nowdays hematite may also be used as a polishing powder and as a paint pigment. Said to be a good healing and grounding stone, it strengthens the body and improve resistantance to life's stresses. Hematite inspire inner life and helps to keep inward peace.
