Want a wedding band that is hefty, tarnish free will still look like a million bucks years later? Then stick to platinum wedding rings as it's exceptionally strong and looks unlike anything else in the market.

What metals go into a Platinum Wedding Ring, exactly?
Typically, platinum, the element, is alloyed with some other metal, similar to the way white gold is an alloy of elemental "yellow" gold and some other metal (sometimes even platinum). In the case of platinum, alloys include palladium, iridium or ruthenium (depending on the commodity price.), however they are used in small quantities in order to maintain platinum's high purity.

Platinum wedding rings are not measured in karats, contrary to gold wedding bands. Look for platinum wedding bands that have "PT 900" or "950 Plat" imprinted on the inside of the band. This means that the wedding ring is 90 or 95% pure platinum, and 5% of some other metal.

Compare this to a typical gold wedding ring or gold engagement ring which will be between 14k and 18k. Translation: As much as 42% of your precious little wedding rings could be made of something other than gold. That's not the case for platinum wedding bands.

The reason platinum is the most expensive wedding band material is because platinum is exceedingly rare. Its 30 times rarer than gold.

An Investment in Platinum
A platinum wedding ring is an investment because you're purchasing the highest quality of metal for your rings - no plating will be required down the road (as opposed to white gold which is plated with rhodium that eventually wears off). Platinum also "feels" like it's worth a lot due to its heaviness. Platinum wedding bands will also not lose any metal as they get scratched or dinged - the metal is just displaced. This contrasts with gold, where every scratch represents a potential loss of some of the metal in the wedding band.
