Stone
Labradorite
Labrador, Canada — and Madagascar
About
Labradorite is a feldspar mineral whose signature is labradorescence — an iridescent optical phenomenon caused by light interference between structural layers within the stone. The effect, known as the Schiller effect, shifts the stone from deep charcoal to electric blue, green, and gold depending on viewing angle and light source. No two slabs are identical. Our Madagascar-source labradorite carries particularly pronounced gold and orange schiller bands.
