This necklace showcases a classic, 3-dimensional molecular model of caffeine composed of lovely, iridescent, Czech druk iris glass of alternating colours to represent carbon, nitrogen, and oxygen and crackle glass to represent hydrogen. Silver plated wire forms the frame, illustrating single and double bonds. The molecules are suspended on a delicate silver plated chain and lobster clasp.
