Jewelry Tumbling Media Introduction

Jewelry tumbling media is specifically designed for deburring and polishing precision metals like silver and gold.

Unlike other tumbling media that come in different sizes, jewelry tumbling media only comes in small sizes such as 12mm and 10mm to produce precision results.

Plastic tumbling media is commonly known as grounding chips. These chips are bonded with polyester and are used for fine grinding silver and gold metals.



The ceramic media is bonded with abrasives such as brown corundum. These abrasive media type are used for the grinding of steel parts.

Triangle and cylinder-shaped are the most commonly used jewelry tumbling media. They assist polishing processes by getting into areas that are hard-to-reach to ensure that the entire part surface is successfully polished and cleaned.

Stainless steel media such as balls, cones, and pins are popular shapes for jewelry tumbling media. They contain no abrasive material, therefore making the wear-and-tear of these types of media low too. They produce high polished finished on the surfaces of jewelry. Stainless steel pins are also ideal for getting into difficult slots and holes of jewelry.

Zirconia tumbling media is sturdy in structure and is made of durable materials. They are generally used in centrifugal disc finishing machine and vibratory tumbling machines to produce best quality results. In addition, zirconia media balls also has a high sense of gravity. What this means is that zirconia media replaces the stainless steel media without causing them to rust.


The dry tumbling process is usually the final stage in polishing jewelry. During this process, natural materials such as walnut shells, wood, and corncobs are used as media during tumbling. The dry media removes any oil, water, or excess liquids found on the surfaces of jewelry. This is a great media for absorption.

Over the past 20 years in the industry, we can proudly say that we develop our media using high quality materials. These high quality materials ensure that we manufacture the best quality media that produces the highest quality results on all parts.
