What is Opal?

Technically opal is SIO2 and a minute trace of H20, bound together in a lattice-work that resembles marbles in a fish tank, all settled in orderly little rows. Because the silica is generally spherical, each tiny particle adjoins its neighbor, but never flat surface to flat surface.

Light passes amongst these particles, speeding up and slowing down as the size of the spheres and spaces between them change with the angle of view. Longer light waves produce RED color hues and the shorter waves produce BLUE color hues.

Whichever way you turn an opal, you’ll be re-angling the direction and the speed of the light-waves as they pass through the lattice and meet your eye. This phenomenon is truly a manifestation of Mother Nature's genius.
