The opal is slightly translucent and mysterious stone, in which the spectrum of colours from milky white to black is represented- reflecting totality. These flashes of opalescent colour and fire can be utilized to reach the highest spiritual levels of inner sight.
This is a very porous stone that can crack and shatter easily. The reflection and refraction of light on the water combined in the stone and tiny cracks of the opal cause the opalescent quality in the shifting colour. It has been considered an unlucky stone at certain times because it absorbs the negativity of an individual and then returns it.
