A Promise, Perfected

Gemstone Cluster Rings

A cluster gemstone ring groups small stones tightly around or beside a colored gemstone so the piece reads as one bright shape. Here the clusters are lab-grown diamonds, set as floral halos, a graduated cluster or shoulder trios. Every design comes in round, oval and marquise, and most in cushion, pear, emerald, princess and heart, in gold or platinum.

Buying guide

Choosing the colored gemstone

  • Lab-grown ruby, emerald, and blue, pink or yellow sapphire.
  • Natural, treated: tanzanite, aquamarine, amethyst, citrine, garnet, peridot and blue topaz.

Lab-grown ruby and sapphire are 9 on the Mohs scale and the hardest choices for daily wear. Aquamarine, blue topaz and lab-grown emerald sit around 7.5 to 8, while amethyst, citrine, garnet, peridot and tanzanite are a little softer and do best with some care.

How the cluster styles differ

The floral double halo opens two rows of lab-grown diamonds around the center like petals. The star floral halo uses a pointed frame over a pave band. The graduated cluster solitaire steps lab-grown diamonds down in size beside the center over an open basket, and the vintage milgrain frame adds a trio of accents on each shoulder. Not every gem is offered on every design, so check the gem picker on each product page.

Size, metal and price

Every design offers 1 to 9 carats total weight, chosen on the product page. Gold comes in 10K, 14K or 18K, platinum is offered on every design, and most also come in Silvadium, a tarnish-resistant sterling silver. Prices start at about $400, and most cluster gem rings are close to $950–$1,000 at their smallest option.
