This is a collection of three charms.
A dendritic agate charm.
A turquoise charm.
And a copper charm that was created by etching my drawings into copper.  I cut out the oval, domed it, and soldered a thick sterling silver wire around it so the copper does not touch your skin.   

The copper is a nice warm contrast to the silver and stones.  And *bonus* It creates a lovely tinkly sound when worn.

My pendants do not come with chain because everyone has a personal preference.  
Any of the chains I offer on my website will work well with this pendant. 

Copper Charm measures:  25mm x 35mm

This is the chain pictured.
