March's birthstone is the icy blue aquamarine, which literally means water of the sea in Latin. Five AAA quality gemstones that are round brilliant cut have been chosen by hand to create this 5 stone band. A 4.4 mm wide shared prong setting is made in the needed finger size. The calming color of the aquamarine gemstones will be showcased beautifully in any of our precious metal options, which includes 14 kt gold, 18kt gold, or platinum. This ring has a total carat weight of 1.50 cttw.
