It's a lot tougher to work with, tougher to polish (!), and has a much higer melting point. A good jeweller will have dedicated tools just for platinum to keep the metals separate and not cross-contaminate. It also needs specific alloy depending on whether it's constructed or cast, for example. So you have to remember that metals are an art material/resource and no artist is going to give you their time for free because lots of work goes into it.
@tripncoins: Your jeweller might take your bar, but will order his/her own stock that is already alloyed because it's a pain in the butt and not everybody has every single tool to do every single task - you have to outsource some things. It's just easier to order stock.
