This is an example of a Labradorite Slice. It flashes small dots of blue and rainbows of others colours.
Labradorite is a useful companion through change, imparting strength and perseverance as it balances and protects the aura. I intuit it to help those ready to raise their consciousness. And it grounds this increase in spiritual energies that they have developed. Use this slice to strengthen intuition and promote psychic abilities.
It is discounted as it doesn’t have strong colours like other pieces. Combine it with a stand for a table or use as a coaster. And if you aren’t into healing help, it is a very cool crystal to have anyway with all that colour. The mystery of Nature impresses once again.
