Many times a basic "6-Claw", or a "Bezel Ring" looks unattractive. We, as professional Diamond Setters must do our best to work and enhance what we're given.
What tools do 'we' need in this exercise?
We need an array of bud-shaped burs from #003, up to #006.
Round-shaped burs, from #003 up to #005.
From a descending order from the 'finished to the beginning', here are the techniques for you need to learn.
With all of the multitude of claws to work on, I prefer to keep this exercise easy for you.
For esthetic reasons, I prefer that the "claw tips" should be rounded using a "#77B Cup Bur" and not shaped like a 'spear' in the front of the claw.
Everywhere that the hand-pushing tool was touching, please use your Pumice wheel #240 to remove any marks in the metal. This means EVERYWHERE, inside the shank and along the outside of the base of the claws!
These claws are extremely high and need to be reduced in height substantially. The claw tips should be just reduced to be above the "Table Facet" of the Marquise stone.
Even if you are setting a cluster of 5 stones. The claw heights should be the same as the "Table Facet" for any ring.
HOW TO DETERMINE THE BEST "BEZEL SETTING" TECHNIQUE?
First of all, DON'T 'HAND-PUSH' THE METAL DOWN.
Please use your Riveting Hammer. This process will give you a uniform flat surface, instead of a rough textured surface that will be so difficult to clean after the setting has been completed.
The best bur size is to use a bur that is slightly wider than the "Girdle" of the stone. The reasoning is that there are areas where the stone could be thicker. This has to be a made available for setting of the stone.
In using the HSS bur, making sure the bur is cutting into the metal at the same depth all around this bezel. (this is not an easy process).
1) You shouldn't use your hand-pushing tool. I prefer (as I mentioned earlier) to use a Riveting Hammer, or a Reciprocating Flex-Hammer.
2) Do not under any circumstances let the "Flex-Hammer, Anvil" get too close to the front-tip of the Bezel frame, (as shown in the close-up). The chances are that breakage could occur here.
3) The very point of the stone is the most delicate area on ANY MARQUISE stone, please handle this area with the utmost care as possible.
4) If you decide to 'hand-push' the "V" metal closer to the point, you may do so now! DO NOT HAMMER WITH A HEAVY DOWNWARD PRESSURE HITTING. You could say "Good-Bye, Gemstone".
If prefer not to 'hand-push' at the tip of the Marquise point. you can apply some 'light hammering pressure' to that Bezel tip. The Bezel must be at filed at an angle all around the frame.
I prefer to have the tip of the Bezel always FLAT, regardless how the stone is sitting in the Bezel.
You can see just where the bearings are being created.
These are the selection of burs when you are carving out the bearing for this stone.
All of the top three claws MUST EQUAL DISTANCE APART. For the widest section of the Marquise, there will be a wider gap, as seen in this photograph.
Where you made a point-bearing is where the point of the stone will be resting against.
In the great photo, you can see just where the point of the stone will be resting against. The round drilling was just 'perfectly created'.
The underneath of the claws needs to be cleared out for the lower section of the stone aka Pavillion.
All of the claws MUST BE CLEANED FOR ANY PROBLEM'S due to any residue of metal from casting.
