US$230.00 This is a spectacular, hand-polished, freeform labradorite specimen (a feldspar mineral) from Madagascar. Its coloration and iridescence are exceptional. The polishing is complete, bringing out natural hues - green, blue, gold, and orange - that shimmer in the light, changing tones and intensity depending on the display angle and level of lighting. Its beauty cannot be fully captured by a camera!Also note that it picks up surrounding colors - so feel free to experiment with its placement. We recommend displaying this piece in diffuse, rather than direct light.Measures 8.3 x 7.63 x 4.3 inches, weighs 12 lb. 10 oz. (5.73 kg).Note: No artificial enhancement of color -- all natural. Labradorite is a feldspar mineral ((Ca, Na)(Al, Si)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.
