I have no idea what one would cost, haven't really seen a full lavender for sale. From reading kingsnake forums where I found that pic, it seems Josh from Phantom borrowed her from Dachiu and was crossing her with some hypo trans leather back projects. I can't even imagine what they would cost but I bet you could get one for around $200. Dachiu imports a lot of different dragons and is always introducing new blood into our population and coming up with some amazing looking dragons. They are very fair priced and super nice people, really down to earth. You can tell it is a true passion of hers because it really shows in her work. If she were to sell one it would probably be around $150, her normal price for a hypo. The dragon I got from them was half Belgium Lavender Hypo Translucent, shes a hypo het for trans I guess. From that I would guess that Dachiu has been crossing lavenders with translucents or working with Josh, seems they go back and forth with a lot of dragons. Must be a cool job mixing all the genetics and making beautiful, live art.
Weird thing I noticed about my ice boy, his body color is very light yellow on is flat scales but all his bumpy raised scales on his back are light grey. At first I thought it was from them casting shadows but its each raisded scale itself.
