The bail is an open jump ring, which will need to be open/closed with pliers to place on jewelry. This listing is for an individual charm only and does not come with a chain. These are natural stones and some internal characteristics/inclusions may be present. Blue topaz is the birthstone for December, making this a great birthday gift for someone born in that month. What is gold filled jewelry? Gold-filled jewelry, has a solid layer of gold bonded with heat and pressure to a base metal core, such as brass. The gold layer in gold-filled items is substantially thicker than gold plated items, and does not flake or chip off. This makes gold-filled jewelry a durable choice, second only to solid gold itself.
