What metal should i get my class ring made from?

im getting a class ring this year, I wanted to get 10K white gold, but it cost to much. So whats better: SilverElite W. Platinum or DualCast metal? silver elite is like a bright color. I like the darkness of the 10k whit gold but I dont know.

If you are not allergic do metals, then if you wish to go more for the lesser value of price, but if you're asking my opinion I think the Silver Elite w/ PLAT looks better than the dual cast metal (I viewed some pictures online) But though if your looking for a less shiney, less costly alturnative then go with the dualcast. Just remember, with time and age how the metal will tarnish... Silver would work better for anti-tarnish.
