Black Opal unset Description:

The term can be a bit confusing because some think that black opal is black but in actual fact, it’s the darkness or blackness of the background that gives the stone its name. So black opals are of the family of Dark opals, whereas White and Crystal opal come from the Light opal family. So, all black opals are dark opals but not all dark opals are black opals. The darkness varies between mid-grey to really pitch black.

Stones like these are becoming rarer as the opal fields are running out. The price of Opal, unlike many gemstones, is influenced by supply and demand, not by international cartels who agree on price increases. Hence, opal is destined to go up in value as the supply becomes more restricted which is happening at present. The color of these stones is completely natural, in contrast to diamonds [for example] which depends on man-made facets to reflect the spectrum colors.
