What is tumbling in jewellery making?

Definition
Tumbling is a process for cleaning and polishing jewellery or gemstones by placing them in a rotating barrel or vibrating bowl along with a polishing media, which is usually stainless steel shot in various shapes for metal jewellery, and a mild soap solution. The constant movement causes the media to burnish every surface of the piece evenly, and the result is a bright, work-hardened finish that would take far longer to achieve by hand. Professional jewellers use it routinely after fabrication, and smaller domestic tumblers are available for home use.
Frequently asked questions
- What does tumbling do to jewellery?
- It polishes and brightens the metal surface by causing the steel shot or other media to gently and repeatedly strike every part of the piece. It also slightly work-hardens the metal, which can make softer pieces a little more resilient.
- Can you tumble gemstone jewellery?
- It depends on the stone. Hard, durable gems like sapphire, ruby and most garnets survive tumbling well. Softer or more fragile stones such as pearls, opals and emeralds can crack or lose their finish, so those pieces should be cleaned by other means.
- Does tumbling remove tarnish?
- Tumbling polishes the metal surface and removes light surface debris, but it does not remove chemical tarnish from sterling silver in the way that a dip or polishing cloth would. For heavily tarnished pieces, a separate treatment is usually needed first.
