Diamond wedding bands provide a brilliant alternative to the classic plain gold or platinum band, whether or not an engagement ring is worn.
Some brides elect to have the solitaire from their engagement ring set into a wedding band; others prefer a wedding band set with smaller diamonds to complement the engagement ring.
Diamond wedding bands allow the jeweler (or wearer) to be creative on a small canvas. These rings can be subdued or substantial, but the common denominator usually is several small diamonds rather than one large one. A "Princess Band"- a row of princess-cut diamonds in a channel setting - is perhaps the most traditional look for a diamond wedding band. Baguettes also look well in such a setting. A stylish alternative is a three-channel band, with a row of sapphires, emeralds, or rubies - sapphires are currently very fashionable - flanked by rows of small diamonds above and below.
Diamonds also lend themselves to more creative, unconventional wedding ring 
treatments. They'll work well with many modern designs, as well as with fanciful ideas such as Celtic knots, or various other motifs that evoke mythological connections.Some of these ideas will allow for the use of a larger solitaire. Many brides also continue to wear the traditional three-stone anniversary ring as a wedding band.
If the bride prefers a plain gold wedding band to accompany her engagement ring, consider a guard ring - a narrow gold or platinum band set with smaller diamonds or colored stones - to set in front of the solitaire.
Diamond wedding bands for men are starting to catch on. Usually the stones are placed at regular or irregular intervals along the band, some distance from each other, and are usually flush-set. A continuous channel of diamonds is an increasingly popular option, though, with round or square diamonds - not baguettes - being typical.
