Natural alluvial (River Tumbled) Jet stone gathered by hand in the mining districts of central Arizona.
Jet is a form of lignite coal which is created by fossilizing wood under high pressure over long periods of time. The variety of fossilized organic matter is clearly visible in most Jet pieces making them each completely one-of-a-kind.
The source of this Jet has features which make it unique among the various deposits of the world. After the sedimentary layer of lignite was formed it was later intruded and altered by volcanic metamorphism. The Jet was literally melted by great heat and exposed to rich metal bearing fluid which deposited large amounts of copper, gold and silver which remained once cooled.
The result of this unique geology is a Jet which contains large amounts of visible native copper, irregular melted shapes and air bubbles (vesicles) which range from minor to extensive. We think you will appreciate it's unique and beautiful character.
Jet has a very long history of being used in jewelry, carvings and all kinds of decorations. It became so popular during the Victorian era that demand greatly outpaced the small supply and countless imitations and "fakes" were produced and sold as Jet. Once you hold a piece of genuine Jet in your hand you will appreciate how unique these stones are and glass, onyx and obsidian do not have the same look or feel at all.
Most pieces have one side which has a natural and often metallic sheen due to the orientation of the material during sedimentary formation. Occasionally pieces look dull on the surface but all Jet can be polished to a mirror shine.
These stones are gathered by hand from river gravel and have not been altered in any way by tools or abrasives. The shapes are naturally occurring - and fascinating!
PLEASE NOTE - These stones are FILLED with native copper - Without exception, every piece which we have cut and polished reveals a rich copper sparkle. Please do not expect this material to finish to a pure Jet Black. The metallic copper glitters easily when polished and will set this apart from any Jet in the world.
