On Monday, we received our first square hearts and arrows cut diamond. It’s just under a carat (0.87ct) and an F/VS1, with excellent polish and symmetry, as graded by the GIA.

Last week, we got an emerald cut in for a client. Although I’m not a huge fan of emerald cuts, as they’re not as bright as brilliant cuts, this one looked nice due to it’s excellent symmetry and seemingly good light return.
