I only have one question. Why do you refer to the item as a black opal if it is blue? I already have a blue one and was looking forward to obtaining a black opal.
If you take a look on the back of the opal = you will see its got a BLACK backing to it, that is a black opal you have. The top of the black opals differ in colour, all colours of the rainbow, but seeing as the opals have a black backing they are called black opals. Responded 16 Jul 2007
