Tension Set Engagement Rings: A Buyer's Guide

A tension set engagement ring holds the center stone between the two ends of the band, so the stone looks like it is floating with no prongs around it. It is one of the most modern-looking ring styles, and it shows off more of the stone than almost any other setting. Here is what to know before you choose one.

How a tension setting works

In a true tension setting, the two ends of the band press inward on the stone and grip it in small notches cut into the metal. Nothing covers the top or sides of the stone, so light reaches it from every angle. A semi tension or tension-style setting looks similar but adds hidden support, such as a partial bezel or a bar under the stone, which gives extra security while keeping the floating look.

Which stones work in a tension ring

Because the band presses on the stone, a tension setting needs a very hard stone that won't chip under pressure. That is why tension rings are almost always made with:

  • Diamond, natural or lab-grown: the hardest gemstone (10 on the Mohs scale).
  • Moissanite: 9.25 on the Mohs scale, with more fire than diamond, at a much lower price. Read our moissanite vs. lab-grown diamond guide to compare them.
  • Sapphire and ruby: 9 on the Mohs scale, for a colored center.

Softer stones like emerald, opal or morganite are not a good fit for a tension setting.

What size stone looks best?

Round stones are the classic choice, and princess cuts also sit well because their square sides rest evenly against the band. Around 1 to 1.5 carats is a popular range: big enough to fill the gap between the band ends, but still comfortable for everyday wear. A 1.25 carat tension ring is one of our most searched styles, available in moissanite and in GIA certified natural diamond.

Are tension rings secure?

A well-made tension ring holds its stone very firmly, because the metal is shaped to press on the stone and keep that pressure. Security depends on precise workmanship, a hard stone and a band thick enough to hold its shape, which is why tension rings are usually made with a heavier band than a prong solitaire. Like any fine jewelry, take it off for heavy lifting or rough work, and have a jeweler check it once a year.

Sizing and resizing

Because the band itself is what holds the stone, tension and tension-style rings are difficult to resize after they are made. Confirm your size before you order: our guide to finding your ring size at home walks you through it, or call us and we'll help.

Tension rings vs. other settings

  • Vs. prong solitaire: a tension setting shows more of the stone and has no prongs to snag on clothing, but it has a bolder, more modern look.
  • Vs. bezel: a bezel wraps metal all around the stone for maximum protection; a tension setting leaves the stone open for maximum sparkle.
  • Bridal sets: many tension rings come with a matching band, shaped to sit next to the engagement ring.
