@MrsCassie:  Nice info. Yes the mineral silicon carbide was discovered in teeny minute amts .However it is much different appearing than what moissanite jewelry looks like today. No gem quality silicon carbide/moissanite exists or has ever existed. Thus moissanite is not an actual synthetic gemstone but a “jewel” as you accurately said.. As you also said,  it’s all created/altered to make it more diamond-like to market as a simulant.  All moissanite is manufactured in the Cree factory. 

It will be interesting to see what happens in 2015 when the patent expires and other manufacturers get in the mix. Prices are expected to come way down for moissanite as they did back in the day with CZ.

And yet…

“Moissanite and synthetic SiC show no morphological differences even though natural moissanite crystals are less than 2 mm in size, whereas the synthetic product reaches several centimeters in size.

The morphological, physical and chemical properties of moissanite and synthetic silicon carbide are in surprisingly good agreement.”

SiC crystal that is used in jewellery today is not altered, it is just one of many different  crystaline structures of SiC  that has similar (IMHO better) optical properties to those of diamond.

The only alterations take place sometimes are colour ehancements that have no effect on luster and brilliance.

@MunsterCat:  look up synthetic SiC to see what that term generally refers to. The C&C product is carefully altered to come out that way.

 Synthetic SiC is a compound of silicon and carbide with chemical formula SiC that grown in a lab. Are you saying that current moissanite that is used in jewellery is not in fact “a compound of silicon and carbide with chemical formula SiC that grown in a lab”?

 

They grow different crystal stucture (different polymorph) of SiC to be used in jewellery but that doesn’t mean it is not synthetic SiC.

Gemgirl is incorrect as naturally occurring moissanite and SiC are very similar. “ Moissanite and synthetic SiC show no morphological differences even though natural moissanite crystals are less than 2 mm in size, whereas the synthetic product reaches several centimeters in size.  The morphological, physical and chemical properties of moissanite and synthetic silicon carbide are in surprisingly good agreement.”

 

Here  is a very intriguing article:

@MunsterCat:  oops. I just repeat quoted the same text. Lol. Such a great scientific read 🙂

@MunsterCat:  +1

The particular polymorph of Silicon Carbide known today as “Moissanite” is in fact it’s own gem. It is not a “jewel.”

The reason why it looks more colorless than most of the rough that occurs in nature is because the growing conditions are better in a lab. The very same thing can be said of lab grown diamonds and other synethic gems which are identical chemically to their natural counterparts yet have better optical properties based on superior growing conditions.

@Kat:  ..no of course its not its own gem. lol its a man made created jewel. D No more no less Do the research. 

the misinformation that circulates here is ridiculous. Moissanite is a diAmond sim no moreno lesz.

@gemgirl6:  Hmm, okay. I only happen to own a moissanite & have done 3 years of research on it.

If you feel so strongly about this, then you must think that lab grown sapphires are similarly just a simple man-made jewel. No more, no less. & if you DO believe that, then I’m wasting my time on you.

@gemgirl6:  nope. It is in fact a gemstone grown in a lab. Same as lab grown diamonds and all the others.

@Kat:  sPp

sapphires exist in nature in the same form as they are put in jewelry. No gem qhality moissy exists or has ever existed. Equating moissinite to an actual gemstone esp a valuable sapphire is ludicrous. sheesh. Enjoy your moissy for what it is, a beautiful sim but the moissy jewel is simply a man made product. Better than a cz but nowhere close to a valuable gemstone

@gemgirl6:  Wow, how rude can you be?

How in the world can you say that moissanite has never existed in nature when there is proof that is has? I would tell you to do your research, although it seems like you already have. Which brings me to the only explanation which is that your personal beliefs have entirely overshadowed your ability to really take in the knowledge.

@Kat:  she said “gem quality moissanite” hasn’t existed in nature which is indeed true.

I’ll duck out now though because these types of threads get insane!

@gemgirl6:  

@letigre:  

Ahh, well no “gem quality” moissanite has been found in nature because they are so small. Also, all natural gems have to be cut and faceted in order to be what most people consider beautiful and gem quality.
