Their vivid and evergreen beauty alone would be enough reason for anybody to choose an emerald engagement ring. Emeralds are not just beautiful but highly valued and sought after stones. The lush green hue that is so typically emerald looks beautiful in an engagement ring. If your lady love has a liking for the color green, an emerald engagement ring would be wonderful. As emeralds happen to be the birthstone for May, and your sweetheart happens to be born in the same month, an emerald ring would be a great idea. Besides being endlessly beautiful, it will also have its strong astrological benefits at play. There is no doubt that emeralds would make a stunning engagement ring especially when coupled with diamond accents. Not to forget it was emeralds that were one of the most favored gemstones of the ravishing Egyptian Queen, Cleopatra.
