This handmade sterling silver barrel pendant is inlaid with blue Lab Opal gemstones. Lab Opal is much more durable than the nature created Opal and that is why it is being used in a lot of the inlay work. The pendant measures 0.47" wide (from opening to opening) and 0.45" from top to bottom. It can either be worn on a chain or used as a charm on a Pandora bracelet. Chain is not included.
