This article is concerned with Ramanujan sums \({c_{\mathcal{I}_1}(\mathcal{I}),}\) where \({\mathcal{I},\mathcal{I}_1}\) are integral ideals in an arbitrary quadratic number field \({\mathbb{Q}(\sqrt{d}).}\) In particular, the asymptotic behavior of sums of \({c_{\mathcal{I}_1}(\mathcal{I}),}\) over both \({\mathcal{I}}\) and \({c_{\mathcal{I}_1}(\mathcal{I}),}\) is investigated.
