In the tension setting, a metal band’s pressure is what holds a gemstone securely in place, instead of using metal bars or claws for that. They are used mostly in standard diamond ring settings. Since the pressure created by a metal holds in place a center stone, the tension setting can be used only with a hard gemstone like a diamond and sapphire.   The diamond is mounted in tiny grooves that are cut into a ring shank’s sides, so the gem looks as if it is floating in the center of the metal band. This unusual appearance is what makes tension set engagement rings diamond settings trendy. There are diamond ring settings that are similar in style to the tension setting. Such kinds of rings use a hidden metal bridge in order to create the dramatic appearance of a real tension setting. They also offer the security benefits of both diamond ring settings – that is, the secure hold of metal claws with a smooth outline of a true tension setting. Another trendy and unique diamond engagement ring setting that does not use metal claws or channels or beads is the invisible setting. In that, a metal that secures a diamond is not easily legible since it is set behind the gem.
