Given the mass confusion about what it is, hows its made, who is even making it, I have to hand it to Less: he truly is the great wizard behind the curtain. So lets pick this apart.
What is the silicon carbide polytype used to create the Amora Gem?
Lets take a look at one of the BTD patents
"The SiC gemstone of claim 1 wherein the SiC is selected from a group comprising 6H, 4H, 2H, and 3C SiC"
6H - Classic Moissanite and Forever Brilliant Moissanite is made of 6H Moissanite. We know its not 6H.
3C - The cubic form of Moissanite! It would be cool in theory because it is not doubly refractive, but the band gap is so low that it can only be a vivid yellow. So its not 3C
2H - Can it be 2H? 2H is promising because the band gap is the same as the 4H so it can be made colorless. However it is 100% hexagonal. What does that mean? 4H and 6H are 50% hexagonal. There is an axis along which 4H and 6H are cut so that the double refraction (hexagonality) isn't seen when viewed through the face of the stone. Given 2H is 100% hexagonal, the facet doubling would be viewed no matter which way you view it.
Therefore what is left? 4H
When BTD launched the AG (4H SiC), it was different than the Moissanite (6H SiC) that was currently available on the market. Therefore the claim that it wasn't "Moissanite" was splitting hairs, but technically correct in that it had slightly different properties than 6H SiC. Less was convinced that 4H SiC was so expensive and difficult to grow that C&C would never carry it, and instead forever settle on 6H SiC given their history of focusing on the cost over quality. The problem was that this strategy was blown to pieces when C&C launched their own 4H SiC Moissanite last September (Forever One). At that point, if AG isn't Moissanite, than Forever One Moissanite isn't Moissanite either.
Faced with this dilemma, what did BTD do? It doubled down on the AG-is-not-a-Moissanite. Given DiamondAngel's absurd rant and numerous misstatements about AG and Moissanite a couple of days ago, clearly she doesn't know WTF it is. Sadly this helps create the Diamond Nexus'like confusion around the AG stone. Of course BTD could just come clean, but the current strategy seems to be working, and colluding with its resellers and forcing them to tow the line lest they be cut off clearly has worked thus far.
Many people assume that BTD is even growing the crystal themselves. A few years ago they bought the equipment to do so, a $500k+ investment, but supposedly it fell flat. At least two sources have told me that they have been buying from Norstel:
as do a lot of the indian Moissanite producers. Norstel sells the whiter 4H crystal Moissanite at a much higher premium. The Indian manufacturers settle on the more yellow rough because its cheaper. BTD buys the more expensive crystal, which is likely part of the reason the AG is so expensive. The irony of this is that Norstel is a former C&C supplier of Moissanite crystal. So much for NOT being Moissanite.
I challenge somebody to ask Less via his forum if the AG is 100% made in the US. Push him to confirm or deny its 4H SiC. And then sit back and watch your post either be ignored or deleted. I have posted similar questions, and my posts were deleted and I was banned.
Over the next year or two you will see more and more Moissanite sources enter the market, and they are only making 4H SiC. C&C is not making any more 6H and is liquidating what is has left. Eventually the only Moissanite available will be 4H SiC. And then what? Will AG still not be "Moissanite"?
On a side note, if you care what GIA says, they wrote a paper in 1997 about Moissanite, what it was and its properties. It discussed the many polytypes of Moissanite, but stated it considered all to be Moissanite given their similar properties. It identified both 4H and 6H SiC, but pointed out that at the time 4H was only grown for semiconductor uses. But I do find it interesting that 4H SiC is really not NEW. It was made and discussed by GIA nearly 20 years ago. However the technology at the time wasn't available to grow it in the pure form it is today.
