Single Stone offers an array of antique and antique-style jewellery. This diamond ring is dated to 1812 and likely was not an engagment ring (diamonds for engagement rings did not really come into favour until nearly a century later). I love the irregularity of the centre stone and the diamond halo surrounding it, as though the goldsmith really let the stone itself dictate the mount, and not the other way around. The imprecision is really lovely.
