The fun of collecting Hidalgo rings is the ability to stack them. Of course, you can’t stack them without choosing guard rings. And since Hidalgo makes so many to choose from, the hardest part will be selecting the ones you like best! All are made in 18 kt. white or yellow gold; many of them have enamel or diamonds. Those from his micro-pavé collection also feature fancy color diamonds or precious stones. See how the addition of guard rings gives your center ring a whole new look.
