Platinum can be very good, as it is stronger than gold or silver, but it doesn't mean that it is the right one for you. Only you will know what makes you happy in an engagement ring. I would suggest doing a lot of internet research before even setting foot in a jewelers. I used Abazias.com when we chose my white gold, .5 carat, princess cut solitaire. I love it, but it took me about 5 months to decide on it. There are a million jewelry sites out there, and most of them offer good information.
