Amora Gem is comprised of silicone carbide, also knowns as carborundum. In that sense, it is absolutely a type of moissanite crystal, albeit the type they grow is different than what Charles and Colvard (the original manufacturers of moissanite) grew. 

When Charles and Colvard started producing gemtone quality moissanite crystals in the 1990’s, they gave it the name “moissanite”, which is the 6H (I believe) crystal polytype (of which there are over 200 for silicone carbide, and like sapphires, moissanite can come in many different colors).  This type of moissanite crystal has a yellowish/greenish undertone, and even in perfect crystal form will never be fully colorless.  

Better Than Diamond (BTD), started growing the 4H polytype silicone carbide, which is truly colorless when it grows perfectly, but imperfect growth formation can result in near-colorless versions of the crystal. In their minds, they don’t want it called “moissanite” because it’s not the same type of silicone carbide that C&C was growing, and didn’t want the two products confused. 

The best way I have been able to make sense of that is thinking of it like sapphire a bit (aka corundum), say C&C started growing blue corundum and named is sapphire, and then BTD started growing red corundum, and didn’t want theirs confused with the other product, so they called theirs ruby. They are both corundum, but different versions with different optical properties. 

Now, other companies (including the ones C&C buys its rough from) are growing 4H moissanite and faceting it in to gemstones. C&C calls theirs Forever One, MoissaniteCo has their own brand, and both are making “hearts and arrows” cuts, which was originally the distinct difference BTD’s Amora Gem was able to boast – precison robotic cutting to a much higher standard (a lot of people did not like the “splintery” look of C&C’s cuts). 

I have seen a Forever One H&A in person, and it was gorgeous! I own the second version of the Amora Gem (amora gem ultra), and the second to last version, the amora gem soaring hearts eternity (pair of 6.4mm each earrings), and helped my brother get a roughly 1ct Amora Gem eternity (the latest version) for his fiance’s engagement ring. The latest version of the Amora Gem is truly spectacular, and is what I am going to get for myself for my next ring, but the MoissaniteCo H&A (called their AGS 000 equivalent or something like that) is also beautiful and I’m not sure I’d be able to easily tell the difference between the two. The Forever One H&A are also gorgeous, and I don’t think you can go wrong with any of the three options. 

***If any of my information is incorrect, please someone correct it! I haven’t kept up as much this last year or so, so some of this could be outdated.

MrsCassie :  thank you for posting one of the best write ups I’ve ever seen on weddingbee. I’m curious about moissanite and you’ve cleared up some of my confusion.

This is a picture of the latest AG cut, the eternity, (F, VVS2), with my AG ultra (the second generation for years ago, G, VS2 – you can definitely see some warmth in this lighting). The older cuts had thicker arrows that were more prominent, but the newest cut doesn’t have that issue. The arrows will photograph darker in some lights, but you don’t see it in person. I also had the chance to review Better Than Diamond’s Takara Eternity – one of their lab grown diamonds, and the AG and the Takara are eerily similar, with the AG’s arrows being *slightly* thicker, but again, the cut is optimized for it being silicone carbide instead of diamond. 

I’ve found moissanite to pick up the surrounding colors a little more than diamond, someone once thought my E, IF old european cut moissanite from BTD was yellow due to the lighting! (It’s not, it is completely colorless).

And my AG soaring hearts eternity (second to last generation) earring compared with the Takara lab grown diamond: 

Here is a picture capturing the “dark arrows” on camera, but again, it doesn’t look like that in real life:

@nivyx Your eternity will be even better! It’s such a close match for the Takara Eternity, it really is, at some point I want to have both to compare side by side , but BTD just posted on their facebook page today they had their first ever return of a Takara Eternity…. because the customer said there wasn’t enough of a visual difference between the diamond and their moissanite to justify the price difference. 

Post pictures when you get it!

nivyx :  I’ve purchased 2 of the Amora Gem Eternity. The first one was truly gorgeous. It was about 7.3mm and at the time I wanted something at least 7.5mm, so I returned it. It’s a decision I now regret. The 2nd time around I got one that was slightly larger at 7.6mm. The 2nd one wasn’t as crisp and gorgeous. It was still pretty, don’t get me wrong. But the first one was much better. ALSO, on my 2nd gem the certificate said E color, but it WAS NOT an E color. I’ve own plenty of moissanite and it looked more like a G-H color. Long story short , I was stupid and didn’t returned it when I should have trusted my instinct. I’ve seen other Amora for sale on DB or LT and I’ve seen pretty ones and mediocre ones. BTD charges way too much for a moissanite in the existence current market’s value and their inventory is fairly low. You would have to wait and wait til you find a listing for the sizes and color you want. Both times, their mm on their certificate is slightly larger than what you actually get once measured with a caliper. It’s something another bee has contacted me about, that when she got it measured by a jewelry it was slightly smaller in diameter than certified for. So pretty much I don’t trust BTD that much anymore. You can get pretty much a similar cut for cheaper prices with the MoissaniteCo’s AGS 000 or August Vintage’s Super Ideal moissanite. This is my personal experiences though.

nivyx :   my first one was 7.3mm and I know another person on PS said their smaller stone was also a lot nicer as well. So I think yours will be beautiful. I mean my 2nd one wasn’t as pretty and crisp as my first, but judging it by itself, it was still a nice stone 🙂 I think you’ll be fine. Congrats on the purchase by the way and post lots of pics for us when you get it.
