Since you mentioned it.. I've done a "process of faceting" picture series, just found it.
It was a test to see how a certain design performed. It later got a "retouch".
attached the rough to the dopstick:
Roughing in the first tier of facets:
Ready to get into doing the girdle, aka 90 degrees slope. It will set the general shape of the stone.
Girdle roughed in:
Now going to a finer lap, to remove the biggest scratches etc.
I then go to 3K diamond and 100K to polish:
Time to re-dop the stone!
After re-dopping the first dopstick is removed:
We may need to fine tune it now, since the re-dopping process can shift the position a tiny wee bit. Using a waterproof marker pen and a known indexed girdle facet:
We're good to go when the polishing lap removes the colour off the whole girdle facet, like this:
Then we repeat the whole process again on the top "crown" area of the stone...
Now I forgot to take some pics, here it is almost ready for a bath in acetone:
Finished test cut, needless to say the design was re-worked:
