A blue topaz halo ring sets a natural, treated blue topaz inside a ring of small lab-grown diamonds. Choose a round, oval, cushion, emerald, pear, marquise, heart or princess cut blue topaz, then white, yellow or rose gold, platinum, or Silvadium, a tarnish-resistant sterling silver. Most designs add pave on the band, with split shank, double halo, floral and vintage looks.

A halo is a border of small stones set close around the center. Here those stones are lab-grown diamonds, and their white sparkle sharpens the blue of the topaz and makes the center look larger than it is. A double halo adds a second ring for more size and light. Many of these blue topaz lab-grown diamond halo rings carry pave down the band, and split shank designs divide the band in two near the center.
Blue topaz is a December birthstone. Most blue topaz gets its color through treatment, which is why the stone is described as natural and treated, and the color is stable in normal wear. It rates 8 on the Mohs hardness scale, so it holds up well in a ring worn often, though a hard knock can chip it. Clean it with warm, soapy water and a soft brush.
Every design offers 1 to 9 carats total weight. Gold comes in 10K, 14K or 18K. White gold, platinum and silver keep the blue cool and bright, while yellow and rose gold give a warmer contrast. Prices start just over $300, and most rings are between about $800 and $1,000 at their smallest option. The style works as a blue topaz halo engagement ring or a halo topaz ring for everyday wear.
