    The rainbow stain is because of oxidation of silicon carbide isn’t it? That’s why the silver polish seems to work. Have you tried ultrasonic cleaners?

    FutureDrAtkins :  I was considering getting a moissy then I discovered that ny friend with a moissanite has a similar problem. She too uses the silver paste. My husband is a chemist and he said that the rainbowy thing is because of a passivation of silicon dioxide on the silicon carbide. It is a chemical process like rusting, so can’t so anything to stop it. I also found out that some people have it, and some dont. It could be because of a coating on the stones, who knows. The moissy companies don’t really talk about it and send everyone a silver cloth, from what I gather.

    It would be interesting to know which stones are more susceptible to oxidation.

    FutureDrAtkins :  that’s very helpful thank you. I have a moissy stone in my stand in ring and I just wanted to know what to look for should it happen to my ring.

    FutureDrAtkins :  I’m curious, do you think the stain may be covered under the warranty  do you think if you sent your stone in they could give you a new one for free? Since yours doesn’t go away?

    I wasn’t even thinking about them not making the stone anymore I was thinking that you got it from Moissanite co.com and that you could replace it with the Moissanite co-brand oec. But it’s the C&C that the warranty is through

    2bee0rn0t2bee :  ooh that’s interesting, that it could be a coating on the stones!

    I have 2 moissanites, one white and one which used to have a pink coat (the coat got lost during setting, so it turned white too…). The white one, despite being older stock, never got any stains, but the once-pink one did get this weird rainbow oil slick! I haven’t tried very hard to get it off though, but I’ll try today with my silver cloth!

    I have a C&C FB OEC as well (also from Schubach’s), and it hasn’t developed a stain. I’ve had it since Nov 2016. Not sure about our water here in DC, but I hardly ever take my ring off, even when working out, showering, and doing dishes. I only take it off to put on lotion or when I’m doing heavy-duty cleaning with chemically products.

    Ugh, sorry bee. Have you tried baking soda and water? I’ve never had it happen to me (I own 3 different types of Moissy) that’s what I use to clean my jewelry (diamonds included), when I’m lazy I just used dish soap but I know that doesn’t work on that issue. Good luck

    I got rid of it with my electric toothbrush! Just 2 minutes with some toothpaste and, holy cow, I forgot how sparkly moissanite gets. Absolutely blinding! A bit sorry I didn’t take a ‘before’ pic to compare now. It was similar to FutureDrAtkins’s photo on page 2, although not as dark. Now:

    I really do hope the people who make moissanite address this issue officially, and be more transparent about it.

    Has anyone noticed how much time passes before noticing the stain?

    I’ve had my C&C FB for 9 months now and still do not have the stain. I wipe off bits of oil and dirt regularly with my shirt, but I don’t use my Connoisseurs frequently anymore. I also still take it off anytime I shower, do dishes, or wash my hands anywhere. We do have very hard water here, which I found out recently.

    I’ve had my ring since April and just noticed a “stain” for the first time a couple weeks ago. Though honestly? It was BARELY noticeable. The way some people talk about the stain, I was expecting to find some awful oily abomination on my stone one day… nope. All it was was that in very bright/direct light, there was what looked like a small smudge on the stone. I thought it was just that — a little smudge. But it didn’t come off with normal rubbing or even with water.

    About 10 seconds with a silver polishing cloth did it. No biggie for me, honestly! I clean my ring about once a week in cleaner (not because it gets dirty, I just really love the moissy sparkle so I like it really clean!) so I’ve just added a quick rub with the polishing cloth to my cleaning routine, even though I haven’t seen the stain since. It adds a little extra shine anyway, so why not? 🙂

    It’s not a huge deal, in my eyes. But I can understand why some people might be bothered. Especially if their stain is more noticeable than mine was!
