Stone setting: setting types and the technique behind a secure stone
From cleat binding to channel binding — how you choose and execute the correct binding
En sten kan løfte et smykke markant, men kun hvis den sidder, som den skal. Stensætning — også kaldet fatning — handler om at holde stenen fast, beskytte den mod stød og samtidig vise den bedst muligt frem. Faget rummer flere fatningstyper, og valget afhænger af stenens facon, hårdhed og det udtryk, smykket skal have.
§Claw setting — most light to the stone
Claw setting is probably the most well-known setting type and is named after the small metal claws that bend over the stone's edge and hold it in place. Because the claws only cover a small part of the stone most possible light gets in and out of the stone which gives maximum shine and reflection — therefore claw setting is a frequent choice for facet-cut stones like diamonds.
§Channel setting — stone in groove
In a channel setting, several stones sit in a row inside a milled channel in the metal. The channel itself holds the stones in place, so there is no need for individual claws for each stone. The result is a smooth, continuous line of stones, often used in alliances and ring rails where you want to avoid protruding claws.
§Tube setting and box setting — more protection
Tube setting surrounds the stone with straight, tube-shaped sides all the way around and protects it well from external impact — suitable for stones that are subjected to a lot of handling. Box setting instead covers the stone's edge (base) completely with metal. This makes the setting very robust, but because more metal covers the stone, less light enters, so the stone may appear slightly darker than in a claw setting.
| Setting type | Usually used for |
|---|---|
| Claw setting | Single stone where most light and shine is desired |
| Channel setting | Rows of small stones in alliances and ring blanks |
| Tube setting | Sten der skal beskyttes godt mod stød og slid |
| Bezel setting | Robust fittings where durability weighs most |
§The process — from goal to finished setting
Regardless of setting type, the work begins by measuring the stone precisely and preparing a seat in the metal that fits exactly. If the seat is too loose, the stone will rock or fall out; if too tight, the stone may crack when pressed into place. Once the stone is set, claws, channels or bezel are carefully closed around it — often using specialist tools that distribute pressure evenly so the stone is not stressed unevenly or cracked.
- 01Always measure the stone before the seat is made — a seat that is too tight or too loose is the most common source of error.
- 02Some stones do not tolerate heat or pressure well and require special care during setting.
- 03After setting the stone should be gently tested to ensure that it cannot move.
- 04Always clean the mounting for putty and metal dust so the stone appears clear and clean.
A good setting is not just seen from a distance — it is felt when you gently try to move the stone and it holds year after year without the stone loosening or falling out. That is the standard you work to as a gold and silversmith regardless of which setting type the task requires.
