Measuring in at only 12 by 7 mm (about 1/2 by 1/4 inch), these little raw copper bezel settings for cabochons might be just what you need for your next project. The inner circumference of the oval is about 10 by 5 mm (about 7/16 by 3/16 inch). There is no hanging loop, so this is perfect for attaching to the front of a locket or other necklace or charm base. Or, add a loop of your own to make it into a charm. Because it is raw copper, you should be able to easily patina it as well.
This component is much smaller than it appears in the illustration, so, please check the measurements.
