Iconic Princess Diana Blue Sapphire Ring in Sterling Silver

The most famous engagement ring in the world, reimagined for everyday royalty. This blue sapphire ring centers a 1.86ct royal-blue oval — a genuine lab-grown sapphire — inside a brilliant halo of simulated diamonds, set in solid 925 sterling silver with a luminous rhodium finish. It is the heirloom Art Deco silhouette made accessible, a piece that carries centuries of romance on a single finger.

The design: a royal halo, reborn

Few silhouettes are as instantly recognizable as the royal-blue sapphire halo. Here, a deep-blue oval sits at the heart of a sparkling ring of simulated diamonds that trace and amplify its color, all raised on a graceful sterling band. The effect is unmistakably regal yet entirely wearable — a design equally at home at a proposal or a black-tie evening. If you are drawn to that storied, jewel-toned look, you will find kindred pieces throughout our sapphire engagement rings collection. If you are weighing this cool-blue classic against another icy favorite, our comparison of aquamarine versus sapphire lays out the differences.

The stone: a genuine lab-grown sapphire

The center is a genuine lab-grown sapphire — real corundum, chemically and physically identical to a mined sapphire, simply grown in a controlled environment rather than pulled from the earth. That means the same saturated royal-blue color and the same formidable Mohs 9 hardness, second only to diamond. It is a stone built for a lifetime of daily wear, and it happens to be an ethically sourced, conflict-free choice. To understand why this gem has symbolized devotion for so long, our complete guide to sapphire meaning is a beautiful place to begin.

A brilliant simulated diamond halo

Encircling the sapphire is a halo of simulated diamonds that adds a crisp, white flash of brilliance and makes the blue at the center glow even deeper. It is a bright, budget-friendly way to capture that classic engagement-ring sparkle without compromising the drama of the design. Prefer more fire? This piece can be crafted with moissanite or lab-grown diamond accents on request — just reach out before you order.

Solid sterling silver with a rhodium finish

The ring is crafted in solid 925 sterling silver and finished with rhodium, the same precious metal used to plate fine white gold. That rhodium layer gives the band a bright, mirror-white luster and adds a protective shield that helps resist tarnish and everyday scratches, keeping the silver looking freshly polished. It is the detail that lets a sterling ring wear like something far more precious. Pair it with a slim band from our sapphire couples rings for a stacked, layered look.

Sizing & care

Choose your size at checkout. If you are between sizes or unsure, we are happy to help — and if the fit is not quite right, resizing is available and starts from a modest fee. To keep the sapphire and rhodium finish at their brightest, remove the ring before showering, swimming or applying lotions, and store it in the velvet box when not worn. A soft, dry cloth restores the shine beautifully. With gentle care, this is a ring made to be worn every day.
