Belle Cushion Cut Aquamarine Ring in Sterling Silver

Picture a drop of calm ocean caught in silver. The Belle cushion cut aquamarine ring centers a 2.5 ct sky-blue aquamarine, wrapped in a full halo of simulated diamonds that catch the light from every angle. Set on a slim 2 mm band in solid 925 sterling silver with a bright rhodium finish, it is a serene, statement-making March birthstone ring designed to look far larger than its slender profile suggests.

A halo built to amplify

The halo is doing quiet, clever work here. By ringing the cushion center with a circle of small simulated diamonds, the setting borrows their brilliance and throws it back onto the aquamarine, so the blue reads brighter and the whole face of the ring wears a full size larger than the center stone alone. It is the trick jewelers use to make a modest band feel like a showpiece, and on this aquamarine engagement ring it turns a serene blue stone into something that genuinely sparkles across a room.

The cushion cut aquamarine

The center is an 8 x 8 mm cushion aquamarine, lab-created for even, consistent color and a clean, glassy clarity that lets the sky-blue tone glow. Cushion cutting rounds the corners of a square and adds soft, pillowy facets, a shape that flatters the calm ocean hue and feels both vintage and current at once. If you love the color but want to compare shapes and settings, the wider aquamarine rings collection is a good place to browse, and our guide to aquamarine versus diamond explains why so many people choose an icy blue center over a colorless one.

Simulated diamond accents

The halo is set with high-quality simulated diamonds (cubic zirconia), chosen for their crisp, colorless fire. They give the ring that classic engagement-ring shimmer at an accessible price, and they frame the aquamarine beautifully without ever competing with it. Prefer moissanite or lab-grown diamond accents instead? Most of our designs can be upgraded on request.

Solid sterling silver with a rhodium finish

Belle is crafted in solid 925 sterling silver and finished with rhodium, the same bright white metal used to plate fine white gold. That rhodium layer gives the ring a mirror-white luster and adds a protective shield that helps resist tarnish and everyday scratches, so the silver keeps its freshly polished shine. It is the detail that lets a sterling silver ring wear like something far more expensive. You will find the same finish across our sterling silver aquamarine jewelry.

What aquamarine symbolizes

Named for the sea, aquamarine has long stood for calm, clarity and steady, honest communication, the sailor’s stone of safe passage and the birthstone for March. It makes a quietly meaningful choice for an engagement, a promise or a milestone birthday, a way of wishing someone peace and a clear course ahead.

Sizing & care

Choose your size at checkout. If you are between sizes or unsure, we are glad to help, and if the fit is not quite right, resizing is available and starts from a modest fee. To keep the halo and rhodium finish at their brightest, remove the ring before showering, swimming or applying lotions and perfume, and store it in its velvet box when not worn. A soft, dry cloth restores the sparkle in seconds. Curious how aquamarine compares to a lab-grown alternative on shine and budget? Our aquamarine versus moissanite guide breaks it down.
