Black Opal

Black Opal is mainly found in Lightning Ridge Australia and was first recorded in 1873. It is the most valued of all opals with a distinct black body tone that distinguishes it from all other types. The grading scale determines whether the opal is black opal, with N1 – N4 being classified as black opal. Although it is generally the most expensive type of opal, many other factors must be taken into consideration when valuing an opal.

Black Opal Rating N1 - N4

Australian Black Opals are non-porous so they won’t absorb any water or oils. Black opal is made from trace elements of iron oxide and carbon present in the formation of the stone causing the dark appearance they are known for. A layer of black potch backing is generally left on the stone to enhance its vibrancy using the same principle that is used with doublets and triplets.
