Granulation

Sometimes the smallest details can completely change a piece of jewelry.

Granulation is an ancient metalsmithing technique that uses tiny spheres of metal—called granules—to create pattern, texture, and dimension. The technique dates back thousands of years and is particularly associated with the extraordinary goldwork of ancient Etruscan jewelers.

From Metal to Tiny Spheres

Granules can begin as tiny pieces of metal or snippets of wire. When heated to the melting point, surface tension pulls the metal into small spheres.

Those individual granules can then be arranged on a piece of jewelry and carefully bonded to the underlying metal. The process requires precise placement and careful control of heat—the goal is to securely attach the granule while preserving its distinctive round shape.

Texture Upon Texture

Granulation becomes especially interesting when combined with other metalsmithing techniques.

In the earrings shown here, the sterling silver itself has been folded to create ridges and valleys across the surface. The polished granules sit above that folded texture, catching the light and adding another layer of depth. The result is a relatively simple design made interesting by the way light moves across two very different kinds of texture.

At the Bench

Working with granules requires patience. They're tiny, they tend to move just when you don't want them to, and heat control is critical. But that's also part of the appeal.

A few tiny pieces of metal can add a surprising amount of character.
