Black Opals Listed With Strong Blue Colors

We have only just listed parcel of black opals with blue colour display
These popular black opals used to be readily available years ago but now that the Cochran opal fields at lightning ridge have been heavily mined they are rare now.
This is because the opal is formed as a Nobby not as a seam opal and nobby opals are hard to find no
Check these good value blue fire black opals
