Prong-Setting Cabochons

Soldering – Stone-Setting

Learn how to use prongs to set a cabochon or other flat-backed stone.  Bezel cups are great, but they can be difficult if your working with a stone that has a unique or angular shape to the edge.  As long as the stone is flat on the back and fairly durable, setting it with prongs could be your answer.  Using a prong setting also allows you to use a fun texture on the silver backing.  The style of your prongs can also vary.  You can craft refined smooth prongs that are sleekly shaped to conform to the silhouette of your stone, or you can melt the ends into balls and go for an organic/rustic feel.  This choice is usually decided based on the look or refinement of the stone.  Either way, this class will show you how to achieve a setting that will fit well and securely hold your stone.
Please note: You may not actually set your stone in this class.  You’ll want to clean/refine the setting to it’s final glory before securing the stone.  You will have instruction on the process so you can do it at home or you can join us for an Open Session class if you feel more comfortable having guidance/supervision.

What will I need to bring to class

You will need to bring a cabochon or other flat-backed somewhat durable stone to work with.  The thickness of the sheet used for backing your stone depends on how you plan to use the setting as well as the size of your stone.  Earrings are typically smaller and you want to keep them as light as possible, so they would use 24ga sheet whereas a pendant would likely be 20 or 22ga sheet. (Please take note that the butane torch limits the size of the project we can tackle.  Plan to use 22ga if your stone is larger than a quarter.)  You will need a piece of sheet that is at least 1/4″ larger than your stone in both width and length.  The prongs also can vary depending on the stone, but in this class we will use 16ga wire.  You’ll need approximately 2″ in length, depending on the height of your stone/how long your prongs need to be.  Depending on how you plan to use your piece, you will need appropriate jump rings and/or findings to assemble it.
