Labradorite Slab Lapidary Stone Slice Cut Rock

Labradorite is a gorgeous form of feldspar named after the stunning labradorescence it displays. It can have a large mix of colors present, and it lights up while turning slowly at the right angle, similar to the Schiller effect. The stunning effect is caused by lamellar twinning inside the crystals, which causes a unique refraction of light within them, lighting them up in the display you see.  Feldspar is an Aluminum Tectosilicate, a crystal byproduct of high silica magma.   Measurements (inches - longest - approx): 4.3 x 1.8 x .23   The last photo has been taken dry so that you may see any defects. The other images were taken wet to simulate polish.
