1- rare blue needle quartz polished These are very rare and super unique. The blue needles actually aren’t needle at all!!!! They are an illusion from something called the “Tyndall effect”. These “rutile” are actually very thin lines of trapped gasses. The Tyndall Effect makes the thin lines appear blue. When light is directed in just the right way, light is scattered by particles in a colloid, or a very fine suspension. This is also similar to Rayleigh Scattering Effect. The blue light that you see is the blue light wavelength that is scattered much more strongly than a red-light wavelength. This is the reason why the sky is blue. Show more
