it is a guitar and i want to play it - the feel wouldn't be nice ether.
for at a lot of pavée stuff we use diamonds in SI1 and top wesselton colour g-h quality - means fine white!
that is way enough and keeps the price much lower.
no one would watch a 2mm stone with a loupe and even then you won't see big issues.
here is a ring in gold 750 with an great emerald, 2 raised triangle diamonds and a lot of diamonds around.
every stone is single enchased! not a cast but truely forged - was a hell of a work!
sorry for the phrase, but the photo really doesn't do justice.....
