Opal is a hydrated amorphous form of silica, with a high water content. It occurs in the fissures of almost any kind of rock.
Opal’s flashing rainbow play-of-color is caused by diffraction of light by silica spheres stacked internally in the stone.
The name Opal is derived from the Latin word opalus-meaning precious stone.
This lovely precious gemstone Black Opal in this semi precious gemstone Black Agate bead pendant comes from Lightning Ridge, Australia.
