Blades of wheat point their way to a splash of blue in this aquamarine engagement ring. Constructed of 18k white gold, the band of this aquamarine ring is trimmed in milgrain and carved seven-eighths around in an angular wheat motif. A round aquamarine sits in the center of nature-inspired rings like this one. This antique style ring is perfect for the woman who prefers not to wear diamonds. This is a new aquamarine engagement ring.
