Did you know a geologist’s favourite dog is a labradorite? This mineral is a feldspar and is named after the Labrador region in Canada – this is where the type specimen comes from. Labradorite is well-known for its optical effect called labradorescence, a vibrant colour display caused by its crystal structure.
