what is faceted percent?

[jalec]

I am looking at a gia certified diamond, and it says

girdle: medium to thick,
faceted(4.1%)

what does that mean?

also, it has a crystal, a needle, and a natural on it. They are small, but what are each of these, and since none of them are on the table, are they ok?

4.1% thickness at the thickest part of the girdle as a % of the diameter.

if diam = 10mm then girdle = 0.41mm

its ok - thickish but ok

inclusions are fine
