Caffeine is a xanthine alkaloid found naturally in tea, coffee, and cacao. It stimulates the central nervous system by reversibly blocking adenosine receptors. Adenosine is a molecule which induces drowsiness.

In this design, nitrogen and oxygen atoms are indicated by text embedded in the spheres and all double bonds are represented.

The pendant is approximately 2 cm (0.8 inches) wide and 2.5 cm (1 inch) long below the loop.

The pendant is 3D printed in 14K gold plated brass or 14K rose gold plated brass, finished with a 45 cm/18 inch long gold plated or rose gold plated silver chain, and is ready for gift giving with a gift box, polishing cloth, and care instructions.
