Labradorite Ammonite

Labradorite gemstones usually have a dark base colour with metallic-looking colour plays of blue, green, yellow, and red. This iridescent effect is commonly known as labradorescence, and is named after this stone. It is caused by internal fractures that reflect light back and forth, dispersing it into different colours.
