Take your date to look at some precious stones – maybe not diamonds yet, but minerals are nice, too. If you’re in the neighborhood of Jussieu university, stop by their museum of minerals, which displays over 2,000 gorgeous samples from the university’s collection. Open afternoons only.
34 rue de Jussieu, 5th arrondissement (small street entrance to the left of the university’s main entrance)
