Last month D.J. Glaser, President of Glendo Corporation, introduced his new “Volcano” stone setting technique in a tutorial in the GRS Online Resource Library. After demonstrating the technique in a copper bracelet, Glaser wanted to explore the use of this setting with different stone shapes and in a variety of metals. This new piece featuring the “Volcano” setting technique focuses on setting an oval-shaped sapphire in a stainless steel key tag.

Starting with a flat key tag 1.9 mm thick and a yellow sapphire approximately 0.5 mm thicker, Glaser first created a seat for the stone by moving the metal out to the sides with his GRS GraverMach and Magnum handpiece. You will notice in the second photo the back of the key tag where the metal has domed up from forces used to create the “volcano”. Once your piece is completed, some light sanding will smooth the surface out so that the effects of the setting cannot be seen from the back. Glaser finished setting the stone in a bezel style, alternating sides to ensure the stone stayed level. The result is a unique setting that adds a new flair to your work.

While Glaser considered this project a success, he wouldn’t call it a commercial success. “I do not consider this technique a commercial replacement for many tried & true setting techniques. It is somewhat esoteric and limited, but an interesting way to do something different. However, one unique structural benefit is that it thickens the metal around the stone which can be important aesthetically and structurally in certain situations.” To learn how you can set an oval stone like this, read the Volcano Stone Setting: Part 2 tutorial today.
