A Fabulous Art Deco Era 10K White Gold Genuine Emerald & Diamond Ring, size 5.25. This Beautiful 10K White Gold Beauty dates to the Wonderful Art Deco Era. The Gorgeous Emerald is a Deep and Luscious Green! The Stone is 6.35 mm in diameter for a TCW of .80 . Surrounded by 10 Genuine Diamonds with a TCW of .30 , measures a size 5 to 5 1/4 on my ring sizer. There is a chip in the Emerald , not uncommon in very old Emeralds as it is a softer stone; the Emerald is also faceted for a Glorious Look! Beautiful!
