Large Labradorite from Madagascar

A large labradorite block from Madagascar, cut and polished along the schiller-optimum axis. The eponymous schiller moves across the polished surface, ranging from deep blue to green, gold, and violet.

Labradorite is a calcium-sodium plagioclase feldspar. The labradorescence is caused by light refraction at microscopically thin lamellar layers in the crystal structure.

The Madagascan deposits in the Maniry region are considered the world's best source for premium schiller material. A gallery-format polished block documents an exceptional piece of raw material.

A Madagascan collector's item with full premium schiller quality and architectural display cabinet dimensions, suitable for reception areas or gallery staging.
