A Promise, Perfected

Aquamarine Cluster Rings

An aquamarine and lab-grown diamond cluster ring groups small lab-grown diamonds around a natural, treated aquamarine, so the top of the ring looks fuller than a single stone. Every design comes in round and oval, most in cushion, emerald, pear, marquise, heart and princess. Metals include white and rose gold and platinum, with yellow gold and Silvadium, a tarnish-resistant sterling silver, on most designs.

Buying guide

The cluster looks on offer

Each aquamarine cluster ring keeps the aquamarine as its focus. Floral designs gather lab-grown diamonds into petals in a star-shaped halo or a double halo. A graduated cluster solitaire steps stones of several sizes around the aquamarine on an open basket that lets light in from below. A vintage design frames the center in milgrain and sets small trio clusters on each shoulder. Pave on the band appears on some designs, plain metal on others.

About aquamarine

Aquamarine is a blue to blue-green beryl and the March birthstone. It rates 7.5 to 8 on the Mohs scale, hard enough for a ring worn often with ordinary care. Its pale color shows off clean cutting, and lab-grown diamonds around it add the sparkle the softer blue lacks on its own. Clean it with warm, soapy water and a soft brush and avoid sharp knocks.

Carat weight, metal and price

Every design offers 1 to 9 carats total weight. Gold comes in 10K, 14K or 18K. White gold, platinum and silver keep the blue icy, while rose and yellow gold soften it. Prices start under $450, and most rings are close to $1,000 at their smallest option.

Made to order

Each ring is made for you in 10–15 days. Shipping is free on orders over $500, returns are accepted within 30 days, and one resize is free within 60 days of delivery.
