The photograph clearly shows that this opal has a dome of some transparent substance over it to protect it and enhance its beauty. It almost certainly also has a backing of some dark swart material. This would make it a triple-cut or triplet opal, not a doublet. 203.59.139.230 (talk) 01:44, 6 January 2011 (UTC)Reply
