Labradorite is a popular variety of the mineral feldspar. It's named after Labrador the most easterly province of Canada on the country's Atlantic coast. The stone was discovered here in 1770.
Known for being exceptionally iridescent, the finest grade of labradorite can exhibit a fascinating spectrum colours. The colours we see are not in the mineral itself but are the reflection of light. Shades of red, yellow, green and blue can be seen in this piece as it reflects light from different angles.
This optical phenomenon is correctly known as schiller or labradorescence when present in labradorite.
The front face of this stone is perfectly smooth and finely polished. It makes an exceptional display piece but does not stand up on its own.
