[QUOTE="talk-admin,The Amora is unique in that it is the only one that does not need a post growth color enhancement among other things. In customer testing, for example, 100% of people immediately spotted the Amora and deemed it as the most beautiful when next to a Phoenix and F1. They then couldn't differentiate between the F1 and Phoenix, except the Phoenix price is much lower. [/QUOTE]
Thank you for clarifying. Although I’m neither a chemist nor a geologist, I’d like to learn more about how moissanite is created. I was under the impression that the 4H-SiC polytype (all 4H) has a shorter band gap then the 6H, and is thus able to achieve “naturally” whiter crystal (C&C F1?) unlike the 6H (C&C Forever Brilliant?).
In other words, do some formulations of 4H still require post growth color enhancement? Further, my online search identified color enhancement as fixing broken bonds. C&C previously coated the Forever Brilliant, but I think they have since stopped this process. If so, is the Amora a “premium” version of 4H with fewer broken bonds that doesn’t require such treatment, whereas the Phoenix requires treatment? Or is the Amora a completely different proprietary polytype from the other 4H brands, and thus the only one not requiring post-growth color enhancement? And is the Phoenix a 4H that is of similar crystal to the F1 or is it a 6H? Want to make sure I’m comparing apples to apples.
With regards to color treatment: I understand the concern for “mined” diamonds; there are those who dislike the idea of clarity- and/or color-enhancements, while others welcome it for affordability reasons. However, most lab-grown diamonds go through some form of color enhancement. Since moissanite is also lab-grown, is additional treatment really that bad, especially if it’s not a coating? Or is color enhancement for moissanite not permanent like it is for diamond? Can the color-enhanced moissanite change color over time?
Thank you again.
