Important Facts about Opal Gemstones

Opals diffract light wonderfully and boast a varying display of opalescent colours. They range from clear and white to a broad spectrum of hues, including red, orange, yellow, green, blue, magenta, rose, brown, grey and black.

Those with red against black are considered the rarest, while white and green mono-tone opals are the most common. When used in jewellery, their natural colour is often enhanced beautifully by layering he gem over a darker stone such as basalt.

Common opals are so named because they are mono-tone, although they would still be a beautiful buy.

The black variety is the most prized and features a dark blue, dark green or black background with a magnificent play of colour. The next most valued in this category is the white variety - it has a light body colour such as white or cream, on which dances a dazzling spectrum of colour. Fire opal is also highly valuable. It is transparent to translucent with a deep orange to red hue.

Other important sources of opal are Ethiopia, Hungary, Honduras, the United States (Nevada, Oregon, California, Idaho) and the Sudan.
