Labradorite is a close-up of the coloured parts of a labradorite. Labradorite is a semiprecious gem that is often used to keep negative energy away. It's a good choice to keep your aura protected and strong.
Labradorite has many lines in it (it's a layered stone). As the stone is semi transparant, you can see these lines are quite well.
Blue labradorite works particularly well on the throat chakra, as does this painting. In spite of being bright in colour, turquoise and green have a calming effect.
