Opal

Opal is hydrated silica and the refraction of light by silica spheres creates a play of colour when viewed from different angles. Do not confuse opal with "opalite" - this is a man-made synthetic stone, usually glass. With regard to colour, please pay attention to the description of the gems as photographing opals is extremely difficult. Hardness 6 (Mohs).
