There is a drop down box for the material on the right hand side. 14k gold and 14k white gold are available in the list. I have not printed it in this material before, so you would be the first to try. I have had some trouble with silver in the past and Shapeways cancelled an order and said it was unprintable. So as a 'first to try', I cannot guarantee that the order will go through, but I don't see any problems with the printability of it. I think the concern was that the sharp edges would not be quite as sharp after polishing. Let me know how it goes and send me a photo if you decide to go ahead with it. Regards, Jason.
