Labradorite Obsidian & Larvikite Necklace
Below is information about the gemstone on the Labradorite Obsidian and Larvikite Necklace.
Obsidian is not a true rock as it is glass instead of crystal. Obsidian is formed only near active volcanoes when lava rich in feldspar and quartz extruded from a volcano cools too rapidly for crystals to form. Its fast cooling environments are along the edges of a lava flow, a volcanic dome, edges of a sill or a dike, where lava contacts water, and where lava cools while airborne.
Obsidian is found in Argentina, Armenia, Azerbaijan, Australia, Canada, Chile, Georgia, Greece, El Salvador, Guatemala, Iceland, Italy, Japan, Kenya, Mexico, New Zealand, Papua New Guinea, Peru, Scotland, Turkey and right here in the United States.
Rainbow Obsidian contains inclusions of magnetite nanoparticles which give it an iridescent rainbow sheen of purple, green, and golden color.
Rainbow Obsidian is the most valued Obsidian by the gemologists and is mostly found in Switzerland, in the Lepontine Alps.
In the stone age, Obsidian was used for weapons and implements, Native Americans used it as arrowheads and the Incans for weapons, mirrors, and masks.

Larvikite is also known as blue labradorite, black labradorite, and black moonstone, but it is not the same. Larvikite has a grey/black background with a chatoyant grey-blue flash. A type of feldspar with a Mohs hardness of 6 to 6-1/2, this striking gemstone is named for the Larvik Fjords in Norway where it was first discovered in the 1880s, and where major deposits are still found. Norway’s named Larvikite as the national stone in 2007.
Mineral Class: Feldspar
Labradorite, named after the Canadian province of Labrador where it was first discovered in 1770, has since been found in Australia, Finland, and Madagascar, Mexico, Norway, Russia, and the USA. Labradorite exhibits such captivating colors that legends arose that the Northern Lights shone down and were captured inside the stone.
Labradorite displays a beautiful iridescent play of colors, which move as the stone is rotated. Labradorite gemstones usually have a dark base color with metallic-looking color plays of blue, green, red, and yellow. This iridescent effect known as labradorescence, is named after this stone. It is caused by internal fractures that reflect light back and forth, dispersing it into different colors. Labradorite is often heavily flawed with internal dark lines and streaks. Handle Labradorite with care, as it is sensitive to pressure and can easily crack or chip.
Chemical Formula: NaAlASi3O8 to CaAl2Si2O8 Sodium calcium aluminum silicate
