Hehe well to be honest, I was very tempted by the C grade because I had read that its appearance closely resembled that of a mined emerald.
Unfortunately, I have certain obsessive compulsive tendencies - weird little twitches and habits - and one of them includes examining the flaws of items that I have.
So I'd probably end up forever staring at the stone from different angles and lights all the while with weird facial expressions lol. Hence why I thought maybe the B grade would be a good compromise.
But if the B grade won't be available anytime soon, I definitely will consider checking out the C grade
