More of a descriptor than a name, omoi means "heavy" in Japanese. These earrings are actually quite heavy to wear, but, more than that, their weight-like structure and metal components give them an overall feeling of heaviness, hence the name.
These earrings are pretty long, and they're constructed of copper findings and copper chain, with tiger's eye and ruby quartz beads. I'm not sure of the metal of the hardware bits-- I'll have to go back to Home Depot, heh.
I really like these earrings-- they're modern, vaguely Steampunk, and they make a bold statement. It just goes to show that you don't need to just use metal made for jewelry when you make your jewelry!
