Tension set engagement rings tend to look rather amazing, as the gemstone appears to be suspended in mid-air. This is because the gemstone is held in place by pressure rather than prongs, a bezel or other ring mount. The tension setting is so-named as the setting is tension-loaded (spring-loaded) to exert pressure onto the gemstone, whilst tiny grooves are added to the band metal to create extra support for the edges of the stone.
If you're choosing a tension set ring, then you really will get a 'wow' response when you present your engagement ring, but there are a few things to bear in mind.
- Before you buy a tension-set engagement ring, you will need the exact sizing of both your intended's ring finger and the stone you want to use before the ring is made. This is because re-sizing actually involves melting down the old setting and starting again and tension settings are calibrated to hold the exact specification of the stone they will hold.
- Only three types of gemstones are strong enough for tension set rings: diamonds, rubies, and sapphires.
- Jewelers do debate whether tension settings are as strong as prongs or bezel settings, but tension-set rings do not lose their spring loading over time. It is unlikely that a stone will drop out of the ring unless it sustains a major blow (in which case gemstone in most ring designs would be in jeopardy).
- If you love the very modern look of tension set rings, but are a little nervous about them, you can choose a ring design which looks (to the casual observer) like a tension setting with a gemstone that's floating, but it actually has a bridge underneath the stone holding the band together.
