That happened to my diamond after I got in the pool with it. It seemed kind of like a greasy film that wouldn’t go away with my usual cleaning methods. I took it to the jewelry store to have it cleaned professionally and it disappeared. Try that and it’ll probably go away 🙂

Someday_Mrs_Maguire:  I’m afraid I don’t know the answer for sure, but I just wanted to know there IS one. I’ve seen it on here a couple times. Something to do with how they hold the stone while they set it (with an adhesive??) and yes, you will be able to clean it off. Just can’t remember how! Wish I did because I may need that, too!!

I think if you get in touch with charles and colvard customer service or moissaniteco they will send you a special cloth to remove the film. This is a regular thing with moissanites and they will know what you’re talking about.

HUZZAH! I know the answer to this question. This happened to some (not many) moissanites, and MoCo says contact them – they will send you a Sunshine Polishing Cloth, which should remove it. Other women have simply used baking soda and/or toothpaste, polished with a toothbrush, and it’s gone.

Take it to a jeweler and get it cleaned up, it should come right off.  Probably due to cleaning agents or lotions/makeup building up on the surface.  Happens to diamonds too.

I’ve had this happen to my moissy as well. For what I have read (and what I have gleened from a chemist’s point of view), is that the rainbow-y, oil slick effect that you are seeing is what happens with silicon carbide (the material moissanite is made of) is exposed to air. After awhile, the air will react with the silicon carbide and form a very thin layer of silicon dioxide (the rainbow color). This may be enhanced with whatever glue that they use to hold the stone during mounting, but it also happens on its own (Mine will periodically come back after I have cleaned it so I don’t think mine was caused by the glue). I got rid of the rainbow stuff by using a slightly acid abrasive, specifically Bar Keeper’s friend (the stuff they use to clean stainless steel). I took a very tiny bit of the powder on the end of a wet q-tip and buffed the top of the stone, avoiding the metal parts of my ring. Then give it a rinse and it’s good to go!

 

If you are interested in learnig more about silicon carbide, the wikipedia page is pretty good. It mentions the rainbow effect in the Structure and properties section. 

 

Edit: Also, sorry for nerding out lol. I just love the Moissanite stone (the science behind it and especially the sparkle) and I just want people to know that the film isn’t a defect and is completely reversible!

Someday_Mrs_Maguire:  A lot of people also said car polish worked. I don’t know that I would be willing to try that, but it’s an option.

Someday_Mrs_Maguire:  UGH. I think this happens with ALL moissy because it happened to me too and I could NOT get rid of it!

BUT, I finally did!! I used “Invisible Glass” which is an auto grade glass cleaner. I poured just a bit into a shot glass, enough to cover the surface of the stone and not really the setting – don’t know what it will do to rhodium plating, and then let my ring soak for a few minutes. I used the rough side of a dual-sided sponge to try and scrub it a bit. It came off after a few minutes of work and hasn’t been back for probably well over a month now.

Someday_Mrs_Maguire:  Silver polish (a blue paste) on a soft cloth and some elbow grease. Worked for me. Good luck!

Toothpaste + a q-tip or toothbrush with a few minutes of rubbing while watching TV works for me. It does come back eventually. When I first discovered it, I read the BTD thread. That’s how I came up with the toothpaste idea. It really bugged me at first, but now that I know I can get rid of it with a little effort, I don’t really care. Also, let’s be honest – unless I were to angle it right and take a picture, no one else can see it.

Does this buildup happen all the time? Is this a monthly maintenance thing?
