An amethyst cluster ring gathers small stones around or beside a natural, treated amethyst so the center reads as one larger, fuller shape. Every design comes in round, oval and marquise, and most add pear, heart, cushion, emerald and princess. Pick white, yellow or rose gold or platinum, and most designs also come in Silvadium, a tarnish-resistant sterling silver.

Buying guide
In these rings the amethyst sits at the center and small lab-grown diamonds are grouped close to it. Some designs form a flower, with the stones arranged like petals in a halo or a double halo. A graduated design steps lab-grown diamonds around the amethyst on an open basket, and a vintage design frames the center in milgrain with trio clusters on each shoulder. A cluster gives more sparkle at the top of the ring than a plain solitaire, while the amethyst stays the main color.
Amethyst is purple quartz and the February birthstone. It rates 7 on the Mohs scale, softer than the lab-grown diamonds around it, so the cluster's raised border helps shield its edges from knocks. The white of the lab-grown diamonds makes the purple look deeper. Strong sun and high heat can fade amethyst over years, so store the ring away from heat and 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; yellow and rose gold warm the purple, and white gold, platinum and silver keep it cool. Prices start under $450, and most rings are close to $1,000 at their smallest option. An amethyst and lab-grown diamond cluster ring suits an engagement ring or a right-hand ring alike.
