Larvikite is Labradorite but with less calcium and no Blue Flash and so the energetic properties have some difference - Larvikite connects you to mother earth, enhances your psychic abilities and is cleansing of your energetic body. 

Yooperite is Larvikite mixed with fluorescent Sodalite - the orange is very bright when a UV light is shone on it. To me this is a great stone for physical and mental energy rejuvenation and focus
