Lightning Ridge Black Opal

Welcome to Lightning Ridge Black Opal providing investment quality Black Opal direct from the mines at Lightning Ridge!

Opal is non-crystalline silica, similar to quartz, but is not a mineral. Its internal structure enables unique diffraction of light to produce white, gray, red, orange, yellow, green, blue, magenta, rose, pink, slate, olive, brown, and black.

Opal contains every color of the spectrum, from deepest and clearest blues and iridescent greens, through to golden orange, red and fuchsia.

Opal is formed from a solution of silica (very fine sand-like particles) and water. In some sandstone outback regions, water passes though the sandstone to form a silica-rich solution that flows to voids formed from decomposed fossils and as the water evaporates, a silica deposit is left. This is repeated over vast periods and from it, and Opal is formed.

Black Opal differs from other Opal as it is formed on a darker (black) quartz-like layer that enables greater refraction/reflection of the light to the top of the opal, especially the reds and pinks. It is the ‘reds’ that are more valuable.
