This boulder opal is exquisite.  All the color flashes opal is known for.  The opal has an inverted dip which causes a unique play of color.  The 18k gold sculpted band is comfortable to the point one forgets they have it on.  If you have been waiting for just the right opal, this may be the one. (but, of course, you can never have just one!)
