We proved recently that a measure on $\mathbb R$, whose support and spectrum are both uniformly discrete sets, must have a periodic structure. Here we show that this is not the case if the support and the spectrum are just discrete closed sets.

Keywords: Quasicrystals, Poisson summation formula, cut-and-project, model set
