I’ve had the film and toothpaste/tooth brush don’t cut it for me. I have to use something stronger – an automotive grade window cleaner called “Invisible Glass” is the only at home product I’ve ever gotten to work. I guess if you call C&C you can get a cleaning cloth that works.

It’s really annoying and the only “con” to moissanite. I’m playing with the idea of getting an OEC diamond because the stain annoys me so much 🙁 I don’t believe them when they say it’s left over polishing glue or whatever – I think this is some kind of oxidation that’s happening on the surface of the stone.

hmmm i have noticed this, but i didn’t realize it was specific to moissy! i really only notice this right by my prongs. i think i eventually want to get an amora gem to replace my moissy (although i have absolutely loved my stone!)- i wonder if this will happen with the amora gem too?

FutureDrAtkins:  Did your stain reappear after you fully cleaned it away?! I’ve only ever heard of this being a residue which won’t come back after it’s properly cleaned, oh dear, that would be super annoying if it kept coming back.

I’ve had my moissanite for more than 2 years and am yet to see this film, but I always figured it’d be an easy one-off fix if it did show up.

I’ve noticed that too on mine! Toothpaste/toothbrush isn’t removing it and I don’t want to ruin my white gold setting, so I’m going to look into something similar to the window cleaner.

LittleAudrey:  Bees I had this problem too – a rainbow stain over my moissanite, almost like an oil slick and nothig would get rid of it UNTIL I contacted moissaniteco and they recommended SILVER POLISH and a toothbrush. This totally merits annoying CAPS because it actually worked!! I use the blue coloured silver polish and a toothbrush and it comes right off. They say it’s permanent if you do it three or four times but I love how sparkly it looks afterwards so I do it once a month or so. Recommend it!

FutureDrAtkins:  See my post above. I don’t know if it’s permanent but it does come right off with the silver polish.

valintine:  Yes! It keeps coming back! Hence my frustration. It’s really the only thing I don’t like about the stone, and it’s why I think it might be an oxidation process and not left over residue. Why would it come back if I cleaned it off and it was just residue? Hmmm. 

DarlingClementine:  That is about the 1 thing I did not try. I’ll give it ago and update 🙂

TrueLove407:  Did your spot reappear after using the cloth they sent you?

FutureDrAtkins:  I too had the stain and emailed Charles &colvard and they sent me the cloth. I got it about 2 months ago and used it and so far it hasn’t returned.

FutureDrAtkins:  nope.. The spot has been gone ever since. But if my rings dirty, I now use the clothe to clean it. It works great!

I get the same stains on my white sapphires, so they’re not specific to moissanites. I can buff them out with toothpaste on a bit of paper towel. I’ve always thought they’re hard water stains, judging by their appearance, the mineral content in the water here, and the fact that I don’t use any lotions or products that could explain them.

I know what you mean by the oil slick type stains. They aren’t exclusive to moissanite stones. I have no idea what causes it though.
