About the bezel setting

A bezel setting is a type of setting where the metal edges wrap around and hold a stone or gemstone in place. It is one of the oldest, most secure, and most popular settings for rings, earrings, pendants and other pieces of jewelry.

The bezel setting is one of the most secure settings for a gemstone as it completely encircles the stone, providing maximum protection against accidental knocks or scratches. As the metal of the setting surrounds and partially covers parts of the stone, this can enhance its color by reflecting light back onto it to give it a more intense sparkle. The bezel setting requires less maintenance than other types of settings due to its design which eliminates any spaces that may attract dirt or debris over time. 

Bezel set stones create a unique look with their modern style and sleek lines; perfect for those looking for an alternative to traditional

Coster diamonds has a wide range of bezel setting jewelry in White Gold, Yellow Gold and Rose Gold.
