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

Buying guide
A halo is a border of small stones set close around the center. Here those stones are lab-grown diamonds, and their white sparkle makes the purple of the amethyst look richer and the center look larger than it is. A double halo adds a second ring of lab-grown diamonds for more size and light. Many of these amethyst halo rings carry pave down the band, while others keep a plain band so the halo stands out on its own. Split shank designs divide the band in two near the center.
Amethyst is purple quartz and the birthstone for February. It rates 7 on the Mohs hardness scale, so it suits a ring worn often, though it can scratch against harder stones. The color runs from pale lilac to deep violet. Strong sunlight and high heat can fade it over time, so clean the ring with warm, soapy water and a soft brush and keep it away from harsh chemicals.
Every design offers 1 to 9 carats total weight. Gold comes in 10K, 14K or 18K. Yellow and rose gold warm the purple, while white gold, platinum and silver give a cooler, brighter look. Prices start just over $300, and most rings are between about $800 and $1,000 at their smallest option. As an amethyst halo engagement ring or an everyday ring, the style works either way.
