Unique in our experience and easily museum worthy. This ring is size 8 ½ with 4.5mm width flat band with broad raised intricately hatched medial. The form is familiar but this example is in as found condition with about 70% or more original gold surface. The darker areas may well conceal even more original gold. It is further distinguished by being made with a central core to distribute the molten metal and heat. The core was then laboriously removed by hand with the remnants still visible. That process is occasionally encountered on thicker rounded face rings but this is the first of this flat section on which we have encountered it. Distinguished by two unique and important features, this ring is truly one of a kind. Jewelry gift boxed with certificate of authenticity.
