The most important thing is to choose a ring that is meaningful and reflects the love and commitment you have for one another. There are many different styles of engagement rings to choose from Pollia's latest collection, ranging from simple and understated to more elaborate and ornate. Some popular styles of engagement rings include solitaire rings, which feature a single diamond set in the center of the band, and cluster rings, which feature many diamonds together. Other styles of engagement rings Pollia offers include halo rings, which feature a center diamond surrounded by a ring of smaller diamonds, and eternity rings, which feature diamonds set all the way around the band.
