Vintage Black Hills Gold Ring, Size 6.25, Coleman, Sterling deals 12K

I enjoy collecting Black Hills gold jewelry and always look for unique pieces. This ring is lovely: it measures a size 6.25 and is tri-color, sterling plus 12K rose and yellow gold. The stone measures approximately a quarter inch long and is a clear green color (lab created), faceted emerald cut (rectangle). It's in deals great shape, set with four prongs and no chips or scratches. The wide band consists of a leaf on either side of the stone, half yellow and half rose gold...the band itself is highly decorated. Inside it's marked: CCO (Coleman Co. of South Dakota) plus STER and 12K. Beautiful ring!
