I have found a home for this lovely necklace:
It is one of my favorite pieces. And I love antique brass. The dragonfly has been hand-patinaed to a lovely blue-green color, and it is clasped by an ornate vintage brass bail. The agate slice further enhances the patina of the dragonfly.
Antique brass oval-shaped links on either side of the pendant for a bit more decorative look than chain alone, and there is an antique brass filigree toggle (not pictured).
I have found it rather difficult to find more agate slices in a similar shape. I guess this one, which just happened to be the perfect backdrop for the dragonfly, was a truly lucky find! I know its new owner will enjoy it!
