A Rainbow in Stone

Labradorite is a feldspar mineral (Calcium Sodium Aluminum Silicate) ((CaNa)(AlSi)4O8). This gorgeous gemstone is known for its dazzling display of iridescent blue, green, gold and even purple colours. The changing flash of colours known as the “Schiller Effect” or “labradorescence” is caused by light bouncing back (diffraction) between internal fractures (lamellae) in the mineral and refracting back to  your eyes.

Named after the Canadian province of Newfound and Labrador, labradorite was introduced to the West by Moravian missionaries, who found the town of Nain Labrador in 1771 and acquired specimens from nearby Paul’s island. The majority of the world's supply of labradorite today is collected on the Island of Madagascar located east of South Africa.
