The bezel setting has a distinct look that immediately suggest solidity, consistence and strength, all great qualities for an engagement ring. It is also the most robust kind of setting and is recommended for larger gemstones over one to two karats.
The bezel enclosure may be too large and prominent for smaller gemstones, although some bezel settings can adapt to smaller diamonds. In general the bezel is preferred both esthetically and security for larger stones. Some designers may argue that if you need to feature a smaller gemstone, the bezel setting may actually make your engagement ring look larger, but in my opinion, it makes the stone look smaller. If budget is an issue, there are less expensive settings that appear more delicate.
The bezel designer will fit the gem within the bezel setting, depending on the model, making sure it correctly fits with the diamond and that is safely holds on to the gemstone.

The most beautiful bezel setting will have a strong hold on the gemstone while exhibiting the maximum possible area from your gemstone. An easy way to test the quality of the fitting is by strongly trying to move the stone with your fingernails. If you are able to move the gemstone in any direction or notice a wiggle, it means the fitting needs more work. The bezel setting main goal is to feature the gemstone as the center of the jewelry.
There are many different kinds of engagement rings settings, and the bezel is at the same time, the most popular as well as the most ancient. Very crude versions of bezel settings include a precious metal collar that is placed around the gem.
There are a few other disadvantages to the bezel setting: it will be harder to clean, as the rim is a magnet for sweat, skin cells, that may make your ring look dirty. You can easily clean the bezel rim with a dry clean toothbrush. There are also special cleaners for the various metals that you can use in conjunction with your tootbrush for a perfect maintenance of your bezel setting.
All in all, the bezel setting is a gemstone classic in all the sense of the term: it has an ancient history, it holds your stone strongly, and it gives a solid look to your jewelry.
