This is very much up to you and will depend on personal preference and your budget. A half or three-quarters set band features diamonds on just the part of the band that is showing and, depending on the size and quality of the diamonds, is normally less expensive than a fully set one. Another benefit is that both half and three-quarters set bands can be resized in the future. A fully set diamond band, meanwhile, is set with diamonds all the way round the band. Many women prefer this style because rings move and twist throughout the day, and with a fully set band the diamonds will always be on show.
