Supposing that you've just finished putting your exquisite diamond into a multi-claw setting.
What is next on your agenda? Let me guide you in this delicate process. I will be showing you diagrams, photos & burs.
==========================
If you need to set a genuine Emerald worth thousands of dollars, I suggest rounding the claw tips first.
This rounding is done with a Cup Bur, aka "77B". As this bur won't cause any setting problems, namely, damaging the Crown Facets of the very soft stone.
Before any large stone is permanently set into a 4-claw head, the seat of the claw must be carved out carefully. Then you should 'pre-polish' and make sure the claws are clean.
If the stone has a wide girdle, as some gemstones have that design, I'd suggest drilling the claws before the stone setting commences.
Always select the HSS (High Speed Steel) that is approximately 50% the size of the stone. This bur size will give you the desired angles into the claws.
Kindly spread the claws, as you need ample space to insert your bur into the claw setting.
As I've written on many occasions, "77B" Cup burs can create rounded tips to your claws.
When you are using these specially designed burs, always keep the inside teeth well lubricated.
