AMENDED SIZE: This ring actually measure 4.5 - 4.75. I have two mandrels..one measures the ring at 4.5 and the other 4.75 but with a heavy shank it doesn't take much to increase the size at a jeweler. This is a very nice ring and I don't often find emeralds. Set in 14K (marked) gold with a diamond on either side of the emerald. Beautiful condition but there is a very very minute chip at the stop of the stone, not noticeable by the naked eye. The gold is heavy with years of wear on it. The emerald measures 1/4 x 5/16 inch. SORRY, BOX NOT INCLUDED.
