Discover the differences in these polishing processes for your fine jewelry creations.
Jewelry finishing is a broad term that includes many techniques — including polishing — that alter the final look of a piece of jewelry. Polishing involves buffing the jewelry with a polishing wheel, tumbler, lap machine, or other materials to smooth out any rough areas and achieve a shine. There are different polishing methods that each offer unique advantages — bench jewelers often use a combination of techniques to achieve the desired finish on their creations.
In this article, we’ll talk about the differences between mechanical and hand polishing processes. We’ll also show you several video tutorials so you can brush up on your skills or learn new techniques.
Mechanical Polishing vs. Hand Polishing
- Mechanical polishing involves the use of motorized equipment, such as polishing machines with rotating wheels or buffing pads, to swiftly and uniformly smooth and shine the jewelry's surface. This method is efficient for handling large volumes or achieving consistent results on larger surface areas, but it might lack the precision needed for intricate details.
- Hand polishing is a meticulous, manual process where the jeweler uses various polishing tools — such as flex shafts, miniature buffs, and polishing compounds, — to carefully polish each part of the jewelry piece. This technique allows for exceptional control and precision, making it ideal for intricate designs and delicate areas that require a finer touch.

Tumbling Machines
Tumbling involves placing the jewelry in a rotating barrel filled with abrasive media, water, and sometimes soap. The continuous movement and friction between the jewelry and the media smooth and polish the surfaces.
How-To: Guide to Tumbling and Tumbling Media
- Rotary tumblers are a terrific option for a quick and simple polish. They leave pieces bright and clean using steelshot media. These barrel-shaped machines roll the jewelry and media together, ideal for polishing larger, less delicate items.
- Vibratory tumblers are versatile, allowing for multiple types of media, such as plastic and organic materials. Vibratory tumblers are very efficient and are excellent for more fine detail polishing. They shake the abrasive media and jewelry together, providing a gentler action suited for delicate pieces.
- Magnetic tumblers are the most common within jewelry stores due to their quick run time and effective burnishing. This method uses tiny magnetic pins that are agitated by a magnetic field to polish even the most intricate details on a piece of jewelry. This technique is effective for reaching areas that are difficult to access with traditional methods, such as inside channels or between prongs in settings.
