What should i use for engagement ring

Hi,

My fiancee promised me to take for shopping of our engagement ring. Undoubtedly I am going to select both of our rings. But I am little confused about what to choose between platinum and diamond. Or a gold ring with diamond on it. Which would be a better option?
Please help.

Thanks!

I didn't find the right solution from the Internet.
