Black Diamond Tension Rings

These black diamond tension rings are tension-style engagement ring settings made for a black center you choose in the next step. The ends of the band reach toward each other and hold the stone between them, so the center looks suspended. Choose from ten center shapes, then white, yellow or rose gold, platinum, or Silvadium, a tarnish-resistant sterling silver.

Buying guide

What a tension-style setting is

In a tension-style setting, the center sits in the gap between the two ends of the band, with no tall prongs or head around it. From the side, light passes beneath the stone and the band looks open. The style is modern and minimal, and it keeps the center low on the finger. Some keep it as a plain solitaire; others add a bezel rim for a little more metal around the edges of the center.

Why a black center suits the style

A tension-style band is all clean lines, and a black center turns it into a sharp, graphic ring. Against white gold, platinum or silver, the contrast is crisp. Yellow and rose gold give it a warmer look. Shapes include round, oval, cushion, princess, emerald, Asscher, radiant, pear, marquise and heart. Rounded shapes give a softer outline between the band ends, while square and step cuts echo the straight lines of the metal.

Metal and price

Gold comes in 10K, 14K or 18K, and each design is also made in platinum and silver. Prices are for the setting only, starting under $450, and most settings fall between about $1,300 and $1,750. The center is priced when you choose it.
