Preparing the seat
- Measure stone and opening; cut seat with burs so the girdle rests evenly.
- Check level and orientation before tightening metal.
Prong setting (basics)
- Seat cut; prongs tapered; push evenly; avoid rocking the stone.
- Inspect under magnification for loose prongs or chipped girdle.
Bezel setting (basics)
- Bezel height and thickness matched to stone profile.
- Burnish / push metal over the stone edge without cracking brittle gems.
