What size of bur to set a "THICK Girdle" stone? => 10 photos.

 What is the best claw setting for a thick-girdle stone? As an experienced Diamond Setter, I primarily look for security of the stone being set. 

 In this essay, I will give you 'my choices' of the head and what claw shapes to avoid and why?

 For a wide-Girdle, there are many limitations in selecting a stone with those dimensions.

                                  Claw settings to avoid:

 'Decorative' and 'Trellis', why? These claws are so very thin and security could be a problem.

 Below is one of the 'best shaped' claws for a thick-girdle gemstone, why? The 'multi-claw' head still gives you the 'decorative' design, but the claws give you the opportunity in utilizing a thicker stone.

 Try to avoid a thin claw pattern, as security is lacking and the tendancy for a claw to move is quite possible.

 If you need a double or triple claw pattern, I'd stay with them.

 I designed this page with text & photos to demonstrate the setting of various claw configerations.

  I drew this (above) page many years ago, I had no idea that it would be used extensively in this particular essay.

 This enlarged diagram explains how a THICK girdle is prepared for setting.

 What size of bud bur is the best size? My answer will be that the thick girdle will sit easily in the claw, as shown.

 Remember; DON'T USE A ROUND BUR. Only use a tapered (Flame-Tip) bud bur and lay it on it's side and CUT ACROSS the WIDTH of the claw.

  How far down from the tip should this carving be? The 'bearing' groove should be no deeper than 1/3rd of height of the claw (as shown here).

 Lastly, => the diameter of the Bud Bur is equal to the thickness of the Girdle.
