What is forging in jewellery making?

Definition
Forging in jewellery is the process of shaping metal by striking it with hammers and forming tools against an anvil, stake or mandrel. Unlike casting, which pours molten metal into a mould, forging works solid metal, compressing and moving it to create the desired shape. The repeated hammering work-hardens the metal, making the finished piece denser and more durable than a cast equivalent. Forging is used for ring shanks and bangles where strength matters, and hand-forged pieces often carry subtle hammer marks as part of their character.
Frequently asked questions
- What is the difference between forging and casting?
- Casting pours liquid metal into a mould, which is efficient for complex or repeated shapes. Forging works solid metal with hammers and tools, which takes longer but produces a denser, stronger piece because the metal structure is compressed rather than poured. Many jewellers use both techniques in a single piece.
- Is a forged ring stronger than a cast ring?
- Generally yes. Forging aligns the metal's grain structure and compresses it, removing the porosity that can occur in cast pieces. For a ring band or shank that takes daily wear, a forged shank holds up well to dents and deformation.
- Can you tell if a piece is hand-forged?
- Often yes. Hand-forged pieces may carry subtle hammer marks or slight surface variations that reflect the maker's hand, and the form tends to have an organic quality that differs from the crisp uniformity of cast or machined pieces. Some makers leave these marks as a deliberate part of the design.
