My H&A MoCo 1ct moissanite has arrived!!!
I haven’t seen it yet because it was delivered to my boyfriend at work this morning. He’s going to wait to look at it tonight so I can see his reaction to the ring (and vice versa). But he has sent me a photo of the imagem certificate.
Now I’m driving myself crazy analysing the certificate haha. It gives me all of the measurements and angles, so I’m wondering whether the HCA tool will be able to analyse it (not sure how much the cut of the H&A differs from a diamond?), or whether there is a different tool for moissanite?
I think i’ll be very very very happy with my moissanite!
Round Brilliant 1.03ct
Colourless (F) VVS2
Light grade – Very Good+
Brilliance – VG 129
Sparkle – VG 61
Intensity – EX 172
Can anyone tell me what the numbers next to brilliance, sparkle and intensity are? Is there an ideal number range?

There is no consumer tool for moissanite, and it does not make any sense to use the HCA for it as moissanite has different properties and needs different angles than a diamond for optimal performance. The HCA was basically designed for GIA graded stones (though you can use on others) to eliminate GIA XXX diamonds that aren’t so excellent. It is not meant for selection, or other types of cuts other than Round Brilliant, or other types of stones like moissanites, sapphires, etc.
H&As are actually a little less brilliant (and also have less “sparkle”) than F1s because the cut is not optimal for moissanite. This is why they are rated as Very Good, not Excellent, for Brilliance and “Sparkle”. This does not bother me as I do not like the usual Round Brilliant cut for moissanite at all (I have H&As, and have had many classic OEC moissanites) and I find they actually are far more comparable to my diamonds in performance. But if you want maximum brilliance and sparkle, an F1 is a better choice.

RayKay : thanks. It’s a shame there isn’t a similar tool for mossanite, but in reality I don’t think it matters as long as I’m happy. I think I’m just looking at the numbers because that’s all I’ve got to go on at the moment! I knew it would be graded very good rather than excellent because of the difference between the F1, and am completely happy with that!
Any ideas what the numbers next to brilliance, sparkle and intensity mean? Is it the higher the better?
