Product details
Precious opal contains a wonderful diffraction grating, formed by the line-up of ultra-microscopically tiny but uniformly sized spheres of silica. The net effects of this array is a three-dimensional diffraction grading, resulting in a spectacular display of spectral colours. If the little spheres are all quite uniform in size and have settled very slowly so as to form a very perfect array, then the colours are the most spectacular known in the gem world.
The image below which was taken under penlight on a black surface reflects the incredible opalescence of this translucent gem.
