weddingbaby12: LOL. Yes, I must be insecure because I actually think every metal has its pros and cons and do not think platinum is right for everyone for everything (nor does my very good jeweler, actually). And it does not always come down to what one can “afford”. Not that I need to lay out my financial situation for you, but I am not even sure what to say about someone who thinks “you must not be able to afford (whatever)” is appropriate to say to ANYONE whatever their financial status. How old are you, seriously?
I actually do have a couple of platinum rings and other jewelery and have nothing against it as a metal but…did you miss the part where I said I have nothing against white metals but don’t like white metals on me? I prefer yellow gold as it matches better with my skin tone and just is more appealing to me than cool white metals. I also don’t wear white t-shirts for the same reason, or perhaps I am insecure and can’t afford a white t-shirt. Sheesh.
Platinum DOES bend, that is why it is recommended for prongs in many situations even if you have a white gold ring. That it bends is considered an asset in these situations, because if you HIT your ring, the prongs or headwill bend and still hold onto the stone hopefully, rather than snap or break (gold has memory and wants to go back to its previous state so is more likely to snap or break). Patina itself is IS tiny scratches – this is platinum patina, see the tiny scratches and dents?:

Some people love that “worn in look”, others don’t and so have them polished by jeweler more often, or even have them plated with rhodium. Alloyed white gold on other hand for example is actually considered to be very hard and resistant to scratching (even if unplated) and therefore stays shinier longer than platinum. Yes, gold does “lose” gold with scratching and so on, whereas platinum displaces, but that does not mean it won’t last a lifetime with reasonable care.
Oh, and since you don’t believe platinum can bend, here are some threads of people with BENT platinum rings:

Gold DOES cost more per ounce than platinum right now, even if platinum is more rare (which I never said it wasn’t). I did not say an equivalent gold ring would cost more than a platinum one, I said ounce to ounce, gold currently costs more than platinum. You can easily look up today’s gold and platinum prices. A 24K gold ring would still cost less today than a 95% platinum ring of the same dimensions because it requires less weight of gold to get the same dimensions because it is less dense. Not that it matters, when you buy a ring you are primarily paying for the workmanship or cost of manufacture and other markups. Try going to sell your platinum ring and getting back anywhere what you paid for it, either as is or in scrap. Same goes for gold. Rings aren’t financial investments, unless you happen to have a massive rare stone (hint: unless you are rocking a 5+ carat flawless diamond or a gorgeous perfect red ruby or something, you aren’t).
As for all your arguments on purity and blah blah. Most people know gold rings are alloyed with other metal so uh, thanks for your brand new information? Yellow gold for example is usually alloyed with copper and silver (maybe a bit of zinc etc), to add strength and hardness to the gold and to make variations of yellow, or rose gold. Other metals can be alloyed to make white, black, blue, green, red, and so on. Your point is, other than to express your lady boner for platinum?
Further, 95% platinum does not mean by volume, it is percentage by weight. Platinum is the heaviest of the metals it is alloyed with, so it actually requires more than 5% by volume of a lighter weight metal to match platinum by 5% in weight. For example, it takes MORE cobalt to make 5% equal in weight than it does of iridium or ruthenium, since cobalt is much lighter. And what it is alloyed WITH does make a difference in how it wears, as I said previously. Some platinum alloys are notoriously soft and more susceptible to scratching.
P.S. one can buff and clean their gold ring at home too. Come on now. But a professional polishing or buffing of platinum is not the same process as a 5-10 minute buff and clean at home. And if someone does not like the worn look of patina, they WILL have to take it in for a professional polishing because a cloth is not going to get it back to that high shine.
