Larvikite

Larvikite is an igneous rock, specifically a variety of monzonite, notable for the presence of thumbnail-sized crystals of feldspar. The feldspar has partly unmixed on the micro-scale to form a perthite, and the presence of the alternating alkali feldspar and plagioclase layers give its characteristic silver blue sheen (Schiller effect, labradorescence) on polished surfaces. Olivine can be present along with apatite, and locally quartz.

Larvikite is usually rich in titanium, with titanaugite and/or titanomagnetite present. The name originates from the Larvik Fjord region in Norway, where this type of igneous rock is found.  It is sometimes called “Black Moonstone” and even “Black Labradorite” based on the feldspar content in the stone and its schiller effect. Typical colours are dark grey, dark blue to black with a blue or steely coloured flash

Larvikite is a protective and grounding stone. It is cleansing to the subtle bodies and facilitates a strong connection with the energies of Earth. Larvikite can help with learning disabilities. It can be used to treat skin disorders and enhances vitality and youthfulness. Larvikite aids in the recovery of strokes and helps brain function. It cleanses and purifies body tissue, harmonizes the metabolism and helps with muscular detoxification. Larvikite calms the nerves and will cool and reduce blood pressure.
