Talk:Opal Dragon/@comment-69.177.243.93-20121001192145/@comment-4874063-20121001194345

Okay, opals are formed when water picks up silica from sandstone and deposits it in crevasses in the rocks or in volcanos. Australia was biggest area of gem quality opals. Now Ethiopian opals, containing less water are best gems. In addition, there are the beautiful fire opals, which are light orange in color. This dragon has the traditional Australian opal as its egg, and is blue, so I would guess a water hybrid is involved. Also, both cold and air are invisible, maybe that is a clue? I just tried lava and rain....8 hour, so no help here. Will keep on trying. Anyone have any luck yet?
