保罗岛
Newfoundland & Labrador, Canada
加拿大拉布拉多海岸外的保罗岛,是拉长石的经典产地——这种带晕彩的长石即以该地区命名。
What it is known for
The Nain anorthosite around Paul Island yields labradorite showing strong blue-green “labradorescence”, the schiller effect that defines the variety.
What collectors look for
Pieces with bold, multicoloured labradorescence — polished or as rough showing a clean flash — are the most prized.
