The charms are based on shapes of the base molecules. They are hooked onto an earwire at the place where they would normally connect to the sugar-phosphate backbone.
This listing is for one pair of earrings. You can choose which two bases you would like in your pair. Please let me know which two you'd like when ordering. If not specified, I'll send a set of my choice.
The charms are about 3/4 inches long, are made with high-quality reclaimed/recycled sterling silver, and are connected to sterling silver French wires.
These come in a pretty, recycled gift box and include an informational card about the molecules involved.
