It took me a while to finish these earrings -- lack of time and not knowing which way to go with the design were two main reasons.
Now it's done -- lo and behold:

I think it will work nicely with the brooch. I will have to wait a while though -- the colours are quite dark and autumn/winter more that spring/summer.

Bigger grey beads -- agate, smaller black ones -- obsidian, smaller red ones -- garnet, also red and black seed beads. Finished with metal bead caps and silver findings, measures 6cm by 2cm.

You can find the earrings for sale on my Etsy shop.
