Right off the bat, I’m going to have to admit that I can’t determine the age of this wonderful copper necklace.  After much research, I can’t come up with any information on the maker, “CH”. 

Enameled white daisies with faceted copper color stones at their centers surround a white glass moonstone cabochon at the center of the copper pendant that hangs from a copper chain. 

The necklace is 16” long and the pendant is about 1 ¼” long and about 1” wide.  There is a tag, signed CH.
