The sunshine jewelry cleaning cloth works wonders ! I bought mine on Amazon.  I started getting the stain on my moissanite about 2 months after I got it….there was build up because I never take my ring off and I use a lot of hair product. I tried the tooth paste, glass cleaner, and the baking soda methods…none of if worked.  The cloth took the stain off instantly !! Now my stone looks perfect again.  So glad I found this thread , it was a huge help !

     I emailed C&C asking how to remove the stain hoping they would offer to send me a cloth (for some reason, I didn’t want to come right out and ask for it, b/c I hadn’t purchased the stone through them)  They told me about it, but said they couldn’t send me one as I hadn’t purchased it through them.  I asked if I could by it, and they endeding up just offering to send me one for free, but it did nothing for mine stone! The stain covered pretty much the entire surface of every facet of the stone.  I finally bought silver polish and I agree with PPs, it works wonders.  My moissanite had had the stain for so long, I forgot what it looked like with about it.  I have been embarrassed to tell people my stone was a moissanite lately b/c of that stain.  Now I can go back to wearing it proudly!  It only took about 15 minutes of buffing it and that doesn’t bother me at all.  Even if it comes back, it was such and easy fix that I don’t really care.

Update on mine: silver polish works wonders!! I’m so happy, it looks so sparkly and white again! There’s some staining left because I used a cloth and had to rush it, but I’ll try again with a soft brush and take my time, I’ll update with pictures soon!

 

Also, boo C&C who never replied to me despite several e-mails.

Vinegar removes hard water spots. Soak it in plain white vinegar.

nicolebee3:  OMG!!! I DIED when I saw your ring (profile picture). Any thread I can see details? Would you mind inboxing me pictures. I LOVE ring porn.

*Sorry not trying to hi-jack thread! I came honestly to learn more about the stain on moissanite. I ordered one – currently un-set – but it was used and I noticed the stain as soon as I got it! I have a very trained eye. I thought it was the double refraction… but was told you can’t see that with the naked eye, or am I wrong? It is not a FB. It is a 10x8mm oval.

This film builds up in layers.  It is an organic film buildup.  It can be removed with a sunshine cleaning cloth or silver paste and an old toothpaste.  If the film is fully removed it does not return.  The bottom layers of the film are clear.  Some may clean their stones and believe they have gotten to the bottom of the film or that is it gone becuase the stone looks much better.  In fact there is still a layer or 2 that must be removed for the film to not come back, ever.  Therefore, when cleaning you should clean it until it looks clean and then clean it a couple more times.  If the film returns then the bottom layer was never removed during the original cleaning.  If anyone continues to have issues then they should contact Charles & Colvard as they have solutions.

moissanitescire:  Shouldn’t the stone be originally sent with no film? If that is the case, then there should be no film for the subsequent layer to build up on, so it shouldn’t happen at all.

moissanitescire:  Welcome to weddingbee, I see this is your first post.

I don’t believe the rainbowy stain is a “build up”, looks more like an oxidation of sorts. Someone here mentioned this (she is a chemist I think) and her moissy has had this recurrent problem. It makes sense. Real moissanite (pic below) is crumble sized and has rainbow irresdence to it .  I wonder if the processing and treatments added to make it white and more diamond like reduce the natural oxidation tendency. Maybe some batches are  mixed differently so they’re more prone to ending up with the oxidation.

It is highly unlikely that it is oxidation and more likely that it is an oil based film.  The iridescent look would lend itself to the science of oil over oxidation.  Any recurring issue would be from not getting to the bottom of the film.  Contact C&C and they can fully explain this to you.  There was much research done regarding the film by Charles & Colvard.  Also, there are no treatments added to make Charles & Colvard moissanite whiter.  Charles & Colvard moissanite is not coated.  The only residue that could or could not be left on a Charles & Colvard moissanite gemstone would be from the faceting process and the wax/appoxy used to hold the stone to the dopping tool.  I recommend contacting Charles & Colvard with any questions as they have the research and most experience with the issue.

Hey all! I just found an easy great way to remove this film or oxidation-whichever it actually is! I don’t know who else has heard of Norwex but they make a whole line of cleaning products. Anyway, they sell these microfiber cleaning rags. The window rag took the rainbow stain right off my mom’s Moissy! I barely even scrubbed. I called them miracle cloths before but now they really really are 🙂 just wanted to share some more helpful info on this issue!
