Dreamy super blue Labradorite from Madagascar

A labradorite block from Madagascar with a particularly strong blue schiller. The polished surface shows a calm base tone, over which the schiller moves in deep blue.

Labradorite is a calcium-sodium plagioclase feldspar from the solid solution series of CaAl₂Si₂O₈ to NaAlSi₃O₈. Labradorescence is caused by light refraction at microscopically thin lamellar layers of different plagioclase compositions. With a strong blue hue, shorter wavelengths dominate.

The Madagascan deposits in the Maniry region are considered the world's best source for premium schiller material. The block was cut and polished precisely along the optimum schiller axis.

Remarkable is the combination of schiller intensity, calm base tone, and balanced block geometry. A Madagascan collector's item in gallery format, suitable for reception areas or the central display cabinet.
