Ooooo, AAA jelly opal sounds lovely! Did anybody get any of the item codes so I can have a butcher's? Was it a special hour, or just a few pieces now and then? I wish Gems would advertise their themed hours better, on their website or on Facebook. Thanks for letting us know about the Ethiopian opal coming up; I have some (from Rocks & Co and from a gem show) and it is gorgeous.
Out of all the opals I have, I think the Mexican (several pieces from Gems TV) is my favourite, but I also very much agree with Meeshoo that opals are extremely variable and it's hard to generalise.
