OK, so they're not real buckyballs - I don't have the beading skillz required for that. But they are close enough.

Six spheroids (in red, orange, yellow, green, blue, and purple) made of seed beads, each attached to a delicate silver chain. They are connected to a wire loop and a clear round glass bead to a stainless steel earwire.

One of the yellow spheres has a thicker silver loop connecting it to the chain due to an error during production, but it is not very noticeable unless you look really closely.

But these fun earrings add some color to any outfit, dressy or casual, regardless of the scientific inaccuracies.

Length: about 1.75 inches from the bottom of the earwire, though there is some variation between earrings and depending on how the chains are sitting.
