Cloisonne lidded miniature vases/jars (5)

As I often do, I picked these 5 vases/jars up at a thrift store without knowing what they were, I just knew they were very unique, detailed, and beautiful. After much research I have learned that the style is Cloisonne and they are: miniature, lidded, and most likely made in China. What I don't know is...what company? Circa? Is that a gold paint or the common bronze? Are they real? Value? A good place to find more info...any additional info would be much appreciated.

Cheers,

Rhonda
