Wow that sounds really cool. I have never seen an albino ramshorn before. Could you post a pic of it so we can see what it looks like? Plenty of people would be interested in buying some if you can start breeding it...
For what it is worth, tetra still sells the brilliants in Germany and Japan. Check the links below;

From what I understand aluminum is safe and stainless steel is iffy.
For instance, if you use a stainless steel mesh to grow your moss all the moss will die, but the moss do fine with aluminum.
