2.74ct. Natural Columbian emerald ring

this is a Sterling silver , 2.74ct. and round faceted white zircon size 6 ring in good condition. the ring is vintage and my jeweler switched out the center stone for me the old stone was a white zircon and it wasn't in good shape so we put this awesome stone in. the ring will come with a copy of the certificate you see with the pedigree and assessment of the emerald used for the ring.
