Polished Blue Flash Labradorite Freeform An upright polished labradorite freeform from Madagascar, displaying flashes of electric blue, turquoise and cool silver-grey when the light meets the face at the right angle. Dark lines and contrasting colour areas give the luminous surface an intricate, almost landscape-like character. The gently curved outline and broad polished face create a compact sculptural accent for a desk, shelf or mineral cabinet. A position where the viewing angle or light changes allows the blue display to emerge and fade, adding movement to an otherwise quiet arrangement. Approximate dimensions: 13.7 × 7 × 5 cm. Weight: 950 g. Labradorite belongs to the plagioclase feldspar group. Its play of colour, called labradorescence, comes from light interacting with microscopic layers inside the crystal; the blue flash therefore depends on the angle of illumination and observation.
