Sometimes a hypoallergenic user will accept stainless steel posts, but I would not think that is what you have. Platinum generally is softer and many firms use 18kt white gold posts with platinum heads so the wires won't bend too easily.
Retailers often seem to live to knock whoever made a sale with you. Putting some fear or anxiety in your mind about what metal was used sounds just like what often happens (all too often). The photo someone else posted with a tiny bit of discoloration where the post meets the bottom of the setting is likely a gold soldered joint and not indicative of what either the post or the setting is made of. Many jewelers use gold solder on thin wire connections such as posts to earrings, instead of using platinum solder or welding. It depends on what equipment they have and what they usually do since it really does not matter in any meaningful way. Basically, the jeweler wants to connect the post and setting without melting the post's end. Gold solder just works at a bit lower temperature and certainly holds very well.
Lots of jewelers plate their platinum with rhodium. There is no special need to do it, but it makes platinum items look just as bright and white as rhodium plated white gold items. Platinum is more difficult to polish than white gold, so rhodium plating helps to even out the appearance.
Like many others today, I do have a fully electronic testing unit for gold which plugs into my iPhone. I love gadgets and this certainly qualifies. HOWEVER, it does not work nearly as well as the old acid and touchstone method I have used for 45 years. It is extremely easy to get false or misleading readings from any electronic tester unit and almost impossible to get such junk results with calibrated acid testing. I wish my iPhone tester was perfect, but it isn't....It is non-destructive, but not the best, most dependable method.
There are x-ray test units out in the world today, too. These are very reliable and non-destructive, but cost in excess of $25,000. Acids are nearly free, so don't expect many places to have x-ray testing any time soon.
To me, you don't have a problem beyond fresh cleaning, re-polishing and a coat of rhodium if you want them to be shiny white.
I'd really like to believe this is just a polishing issue, but I don't think so. My picture doesn't show well what I see IRL, but the post is just obviously not the same...
The posts are not stamped. I do believe (though I'm cautious) that the baskets *are* platinum---they have the weight that my other platinum piece does. The posts are in no way white enough to be platinum (even the most patina-d sections of my ring look better and whiter). I have several pieces of rhodium plated white gold, and my wedding set is unplated white gold. The studs don't resemble any of them, unfortunately.
I am less concerned about "shiny white"--after all, nobody sees the baskets since they are against my ear. But I don't want to have reactions to them.
