Most people when buying men’s rings don't realise that there are quite a few options to consider - shape of the ring, finish of the ring, stones or not. These all come back to what a man likes and what they do every day.
A great example of this is an eternity band with a diamond or a sprinkling of diamonds or other precious stones. A mechanic would not be a great match as the oil and grease would ruin the ring. Similarly - a swimmer would not wear a ring that would be affected by the chemicals in a pool, think a 9 karat ring where it is 9 parts gold and 15 parts other metals.
Court shaped - A flat-shaped ring with slightly convex edges on both the inside and outside is a comfortable option for everyday wear. Court-shaped rings are the most popular and traditional choice in the wedding ring industry.
D shaped - The D-shaped ring has a cross section similar to D. This is due to its curved exterior and flatter interior. With a rounded outside and flat inside of the band, the D-shape ring is softer than the flat shape and fits snugly on your fingers.
Flat or “Pipe Cut” - A popular wedding ring type for men is pipe cut or flat wedding bands. The inner and outer edges of the ring shank are flat in this case, rather than being somewhat rounded.
Then we need to look at the finish - most rings are high polished, but you also get stone or brush finish, sandblast finish, hammered finish or a satin finish. The "finishing" of the ring is the final surface treatment that is done by hand, each with its own unique look and character.
The satin finish - ring feels as smooth as a polished ring. However, you cannot see the reflection on the surface of the ring. ... this type of finish is perfect for those who like the smoothness of a polished ring but don't want the luster of a high polish finish. ...
Matte finish - this finish reduces the reflectance of the metal and the lines are often coarser and deeper than the brush or satin finish method. The cost of this popular finish is negligible.
Sandblast finish - Sandblast wedding ring textures can be gritty or grainy texture. It is as if the surface of the band was blown off by sand and grit. This finish can get caught in the material, but if you need it, you can easily fix it with a clear coat.
A man who works with his hands in an area where there is a lot of dirt may find that a sandblasted finish looks dirty after a little while as tiny pieces of dust get into the finish. Someone who is outdoors a great deal, or spend a lot of time driving may not want a shiny ring that could reflect light into their eyes (or the eyes of their co-workers). Some men may prefer the understated style of a satin finish.
