The Rate of Difficulty is measured by the problems that could occur. I'll place this essay at 25, out of 10. Each photo being shown
could ultimately lead to more problems, I'm here to avoid these situations.
============================================
1) For the first instruction, always closely examine the gemstone for any breakage (anywhere). The 'corners' could be the first place that these might occur.
2) I would use a Bud-Shaped bur to initially enlarge the round hole.
3) Drill the hole vertically, then rotate the bur until the hole gets to be larger.
4) Use "Medium" grade emery paper to remove the unwanted bur-edge.
5) Select a Bud-bur that is 70 =>80% the size of the stone.
6) Calculate 'roughly' by site, how large you should open the hole, but not same size.
7) SELECT A STONE THAT HASN'T A THICK GIRDLE. This stone being displayed, is too wide.
8) Scribe in ink where the corners will be situated. This is exactly where there corners of the stone will be eventually cut & drilled.
9) Clean the 'flat surface', remove as many of indentations as you can.10) This ROUND bur is too large, either select a smaller stone or a smaller bur, but some changes have to be made...HERE & NOW!
11 ) Always keep a wide supply of burs in case of sudden changes.
12) =>Be careful of what burs you are choosing, one error or mistake, could lead to many problems.
15) Please use a large round bur to clear more metal for the Pavillion
17) Examine for any defects 'at the corner facets'.
18) The corners of the stone MUST BE EXACTLY WHERE YOU 'SCRIBED' IN THE METAL.20) THIS IS EACTLY WHAT WE ARE AIMING FOR...A SQUARE HOLE.
26) SELECT WITH THE UTMOST CARE a round bur that is slightly larger than the Girdle of the stone.
29) NEVER...NEVER allow the Culet of the stone to protrude, as seen here. Always select a thicker wedding band that you are eventually designing.
30) Paint the surface of the ring as a reference to your 'anvil hitting'.
31) Use your light-weight hammer at the sides where the hammer has 'touched'.
32) Now you can hammer at the 4 sides, but not at the corners...yet!
33) Gently hammer the metal down on the corners. Now with the paint being removed, you can see where the hammer touched. GREAT IDEA, EH?
34) I would at this stage of setting, gently & evenly tap all around the 4 sides.
35) Keep the 4 inner walls of the bezel, in pristine condition.
36) "Bright-Cut" the inner bezel wall.
37) GENTLY remove ALL of the little defects that remained from the hammering.
38) This diagram explains in better detail what has transpired during this long & difficult setting process.
27) Connect (or join) the '4 spots at the corners'. This where the stone will now rest, or sit.
28) This is the ultimate resting place of the square stone. You can now understand why all of the 'horizontal drilling' was being done.
