A polished labradorite tile with a rare and striking purple flash — one of the most sought-after colour expressions in labradorite collecting. At 18.1 x 18.0 x 1.1 cm and 851g, this is a substantial slab that displays the full spectacle of labradorescence across its polished face.

Labradorite is a feldspar mineral celebrated for its optical phenomenon known as labradorescence — an iridescent play of colour caused by light interference within the stone's internal structure. While blue and green flashes are common, purple labradorescence is significantly rarer, making this tile a standout collector's piece. Depending on the angle of light, this tile shifts through violet, purple, blue, and gold.
