How to drill into "V-shaped-Claw" settings => 6 photos

  This "three-sided stone" has many problems to watch for.

====================================

1) When holding the round bur, it is advisable to keep that bur in a horizontal position. You must allow the bur to drill & cut DEEP into the metal. The placement for the first bur drilling is in the Centre of the "V" claw.

2) Sweep the round bur along the cage of the basket, leading one claw to the next. This is where the Pavilion of the stone will sit.

3) When you are drilling into the claws, always be cognizant of the point of the stone and where it is sitting. In this photo, there is a slight error as one drilling point is higher than the other. This will lead to a permanently crooked stone.

      

 4) I suggest you use a Bud Shaped bur to excavate the metal, as this will give you lengthy cutting along the basket. There should be little or no metal touching the stone.

         REVIEW OF IMPORTANT "BUR CLEANING" FACTS.

 I would (as an accomplished Diamond Setter) use a long-shaped bud bur. I need to have the bur laterally slice off a LONG & DEEP cutting of metal in between the two V-shaped claws.

  The inside edge of the 'basket' needs to be made thinner. The reason is that the Pavilion of the stone must NEVER TOUCH the metal. 

  The size of the round bur must be larger than the dimensions of the combined angles of the Triangular stone. 

Another piece of information is to prepare a lateral seat for the Girdles of the stone on EITHER SIDE OF THE ROUND BUR SEAT. Basically, no part of the Triangular stone should rest upon metal where no bearings have been made.

 "Diamond Setting" is one of the most labour intensive skills within the jewellery profession.

 If you are hesitant in doing any of the techniques being shown anywhere in my tutorial blog. Don't try and do these for yourself. Give your jewellery to a qualified stone-setter and avoid any problems. Gerry Lewy!
