Very fine Georgian blue enamel mine cut diamond ring. This ring is not hallmarked but tests with acids for 18K yellow gold. The top has tiny seed pearls (tears) and 18 rose cut diamonds. The cobalt blue enamel is champleve enamel, where the design behind the enamel was etched by hand and then the translucent enamel was placed over it. On the inside there is hand engraving that says " Emily Dawson Obt. 6th Mar 1789".
