I think Emeralds and yellow gold enhance each other. Here you have a contemporary 1980's 14K gold band with 9 round faceted Emerald stones.
I believe the Emeralds to be natural as you can see the inclusions characteristic of genuine Emeralds.
The ring is size 7 and 3.1 grams in weight. The TW of the stones is @ 0.45 CT. The ring has great color and would be a perfect alone or if you like to add color to a stack of rings.
