🌈 Interesting internal rainbows in this neat Calcite specimen from Santa Eulalia, Mexico! Light bouncing through calcite bounces off interior fractures and planes, acting like a prism and splitting white light into its spectral colors. Calcite exhibits strong double refraction (a single light ray enters the crystal, and is split and refracted as two polarized rays); in this piece, you can see this famous “doubling” of light rays as a shadow rainbow behind the first one. Melty texture and high c
