(Closed) Moissanite… do they hold up?

My jeweler’s words were “I hate moissanite.” He has no objection to using stones other than diamonds (ie CZ) so he’s not one to try and “sell” a diamond. He says it is difficult to get the green color out (albeit not impossible), but often a tint remains, and getting that green out makes the stone brittle and more fragile.

Having said that, it’s a personal decision. Many women here are very pleased with their moissanite stones.

If you are looking at a diamond alternative, my jeweler would recommend using a high quality CZ over moissanite. A truly high quality CZ can give even the best jeweler pause when examining it. White sapphire is an option as well.

I’ve spent months designing a ring with my jeweler, so we’ve had a lot of interesting conversations, haha.

It really comes down to personal preference. 🙂

I think they are “durable”, although I do have a theory fwiw about chipping. They seem to have a thin girdle and shallow crown angle. I believe any stone is more vulnerable cut this way, though.

If you are considering moissy and white sapphire as diamond alternatives please note that neither one of these look totally like diamonds.  Moissy will be more rainbowy while white sapphire will have more white flashes and require constant cleaning.

 

moissy’s a 9 on the MOHs scale, meaning it’s durable enough for everyday wear.  silicon carbide’s been used for years in industrial use, so it’s not an untested material.  Silicon and carbon are both elements happiest formining 4 bonds, so when crystallized it should have a very stable structure similar to diamond.  

 

@crescent:  I think you’re right about Your cutting theory.  When the amora gem comes out, though, this should not be as much of an issue anymore Since it will be offered in more standard cuts.  I will say, though that plenty of women have moissy and don’t run into chipping issues and it’s quite common for even diamonds to chip.

In regards to MOHs I’ve heard Moissy is 9.5 so harder than a sapphire but “softer” than a diamond.

I have a friend who had her >2carat 50K diamond crack in half as she knocked it against her FI’s watch while they were walking.  Diamonds are slightly more durable than a Moissy but setting and cut have a lot to do with which diamonds can hold up better.

I’ve gotten flack for mentioning this before, but there is a noticeably high ratio of mentions of chipped moissanite:moissanite threads on the bee. Considering diamonds are the much more common choice, it’s interesting that there are far fewer chipped diamonds mentioned, and when they are, they tend to be heirloom diamonds, not new diamonds that chipped. You would expect that new diamonds that chipped would definitely be mentioned at least as readily and probably much moreso, as they tend to cost a great deal and so we tend to have high expectations for their durability.

I have not noticed a high amount of chipped stone threads for other less-conventional stone types, such as sapphire.

My impression is that there is a brittleness (not hardness/softness, but rather brittleness/durability) issue with synthetic moissanite. I have also noticed that they tend to chip in a specific way: shattering. This means that for larger stones, a large portion chips off at a time, with shattered fractures inside the remaining piece, on the edges of the chip. For smaller melee stones, the entire melee stone seems to shatter and the owner tends to describe the whole stone to have an overall cloudy look as a result.

This is just what I’ve noticed as an observer on the bee. I don’t own moissanite myself.

Is enhanced moissanite a lot better than non-enhanced? Can you see a lot of green in non-enhanced?

I’ve had my moissanite for over a year now and have accidentally hit it on counters, work out equipment etc and it’s still in great shape. I do have a 6 prong setting which might help a bit.

@FutureMrsV2016:  most of the newer moissanite is not green, but if you go look at it where they sell older stock then it might be green. Size and cut makes a huge difference as well. They say that round stones less than 1 carat you really can’t see any color difference but with larger stones it’s safer to get enhanced stones. I have an enhanced round brilliant that is 1.5ct and i don’t see any color in it unless I’m in yellow lighting.

@joya_aspera:  yes, you’re right..here is one source that mentions it:

http://gemologyonline.com/Forum/phpBB2/viewtopic.php?t=7332

Initial posts are older but posts at the end are from last month. It’s a lapidary mentioning cutting moissanite.

I’ve read about Moissanites brittleness from another source as well. The treatment to whiten it to better mimic a colorless diamond exacerbates the brittleness.

If I were buying moissanite I would probably bezel set it or have at least 6 prongs to guard against chipping. You’re right, there have been several posts I’ve seen in recent months about chipping. Of course any stone can chip.

I would recommend obtaining jewelry insurance through Jewelers Mutual (if you live in the United States or Canada).  Their rates are really low, they cover Moissanite, and their claims and replacement process is a breeze.  In addition to being covered against damage it would be covered against loss, theft, fire, etc.  Also I know that our company offers pretty deep discounts on the replacement of chipped stones. 

Our company has been selling Moissanite since 2005, and far less than 1% of the stones chip or scratch.  It does happen but its also very rare. 

As far as ‘enhancements’ making the stone more brittle, I would like to see where these sources are getting their information and what kind of testing has been done to make such a determination.  With the Amora process for example, the Moissanite stone is whitened via an HPHT process that fixes broken atomic bonds in the crystal.  It results in a more perfect Moissanite which has been tested to be slightly harder (not extremely harder, about 1.5%).

@mikec:  Thanks for the info. Appreciate it as you’re an authority since you sell moissanite. I don’t want to convey negative information, so glad of your input. I’ll try to find where I read about the brittleness related to the treatment. Here is one article I have seen that mentions the intrinsic brittleness. Have also seen things at Investorvillage as well. Plus there was one thread I saw about moissanite where you weighed in as well.

Well my first moissanite did this after four hours of wearing it and hitting it (lightly, not like full on Hulk smash) off a wooden desk:

 

 

 

 

 

 

The company told me I received a dud stone and replaced it. I’ve had no problem since
