I don't think green in moissanite in general is very pronounced, but in my RB moissanite I certainly noticed it in a few different lighting situations.
The OEC seems to show less green (by board concensus) than the regular brilliant cuts in moissy.
I just didn't want to take a chance.
Yeah, the guy who has my OEC right now let me know once he received it that it was gorgeous. He works with moissanite fairly often (mostly rounds) and was quick to let me know, without any prompting, that it did not seem to show the same degree of undertones he often saw (specifically the green).
However, I also add that I did not mind the "risk" of seeing a bit of green now and then as I like stones that are a bit moody and with colour (and I like green!).
I have looked at the photos and videos of a LOT of moissy OECs, both with and without Amora, on here and elsewhere, and hands down everytime I am just more drawn to the unenhanced one. If I see a bit of green now and then in trade for a stone that I seem to be far more drawn too anyway, well, it is worth it!
And I would LOVE to see more buttery yellow in it!
However, if I preferred colourless stones, or as close to it as I could get, and did NOT want to deal with any (or as little as possible) moodiness at all, I would have gone with Amora.
