If your intention is to set this stone in a pendant or ring, the same principles apply as when you set any crystal opal. As you can see towards the end of the video; there is some transparency with this opal. It is therefor best to have a closed in backing on this opal to trap the light in which will enable the patterns and colors to show at their very best.
