This is a nice Georgian diamond band. 3 of the diamonds appear to be table cut--two clearly are. One of the 4 may have been table cut and it may have been chipped at the top, or it could have been a rose cut. The ring is set in 18 k gold with the diamonds being set in silver with closed backs. The ring contains 4 rose cut diamonds, and it is a size 8. It could be resized by someone used to working with antique pieces. It is circa 1810, and it weighs 2.09 grams.
