Its a good question David.
The last time I enquired I was told they are basically unaffordable! So from that I'm guessing 10K and above, there are now white ones with yellow patterning which are even more, where will it all end lol!
Now its no secret that I am a huge lover of Pearl Stingrays, I have many in my collection which I breed from however whilst I'm not usually over impressed with fish in their albino state I have to say with Pearl Stingrays none of the appeal is lost aesthetically, they still retain a beautiful bold pattern, personally I would love to own one but at the same time not afraid to say they are sadly well out of my reach from a financial point of view. The thing is only the very rich can afford animals with such ridiculous price tags which is a shame as having loads of cash at your disposal doesn't make you a good fishkeeper does it, sure having cash doesn't necessarily make you a poor one either but to think such a creature could finish up in inexperienced hands is certainly a worry!
At the end of the day the price has to come down, might take 3 to 5 years but one thing for sure is it "will" come down. Surely there can't be that many wealthy ray keepers worldwide that have the urge to buy albino Pearls, once the inevitable happens more of us will be able to enjoy this beautiful ray.
Sorry I can't give you a specific value, maybe someone else can chip in.
