How To Set Cameos and Cabochons
Here's a tip on how to set flat-backed stones such as cabochons and cameos. When setting these stones, it’s important to keep the gem level as you set the stone.
The bottom of the stone will sit in flat bezel or ledge; make sure that the setting is clean of debris and is perfectly flat and level.
Watch the stone as you adjust the prongs or bezel in case the moving metal should shift the stone.
Correct any problems right away.

Clean stones with hot, soapy water.
Dry stones thoroughly with a soft towel.

Rub gemstones with a smooth, soft cloth to remove fingerprints and environmental contaminants, keeping them bright and shining.
Store stones away from intense heat and light.
