Dopamine Earrings: did you know that dopamine is directly responsible for the feelings of pleasure, personal satisfaction and even, romantic love? A crafty little thing. Now you can wear it as well with this remarkably clever range of jewellery. Suffice to say, it's been inspired by none other than the Organic Chemistry textbook itself. A lovely gift for anyone related to a chemical or medical profession. It will make a very stylish addition to your outfit and be the talk of the evening.
