‘Unset opal’

This means that the stones are not set into jewelry. In other words they are cut and polished ready for setting

Dark opals are found in most of the other opal fields including Lightning Ridge, Andamooka and the Queensland opal fields. Actually all Australian opal is similar in structure. The various types are categorized by what they are associated with. If the crystal opal has black potch in the background, it’s black opal.

If it has dark brown to black ironstone in the background it is black boulder opal. If it has darkness within itself it becomes black crystal.

Please feel free to discuss the stone with us before purchase to make sure you understand the color status.
