Rubies come in many distinct hues of red and are cut in all distinct ways, each shape being more distinctive than the other. The rarest ruby deposits are found in marble, and they are intense red-colored.
If you are looking for vintage ruby diamond rings, then the three-stone setting is certainly one worth considering. Jewelry makers and designers use this popular and traditional engagement ring setting in two different ways. In some ruby and diamond rings, ruby is the center stone while the diamonds have side stones. On the other hand, there are ruby and diamond rings where the diamond is the centerpiece gem and rubies are used as side stones.
