This sculpt is called the "Hatching Empress". She is covered with 23k gold leaf, with a touch of brown airbrushing to bring out details. Nothing else looks quite like real gold. This dragon was sold on ebay.
This is a cast gypsum reproduction of my original sculpture, produced by Windstone Editions. [link]
Several people wondered what this sold for, so I looked it up. We auctioned three of these for an average of around $1,300 ( US) each.
