Hi bamaboy, my lfs
guy has his own diver in far north Australia. He has only had a shipment of this rock twice- the first shipment sold out in 4 hours and I was there when this one came in....all sold by the next day! All pieces were beautiful, some nicer than mine but I just couldn't afford them. I have only had it about a week.
The diver charges whatever he wants....because the area where this rock comes from is inhabited by saltwater crocks. Infact the last diver was taken by a crock last year!
ZooFishMaster...maybe the above explains why you haven't seen more pieces like this.
