Princess Cut Lab Grown Ruby Engagement Ring in Sterling Silver

Bold, square and unapologetically red. This princess cut ruby ring centers a substantial genuine lab-grown ruby — a real corundum stone with the deep, saturated color rubies are famous for — edged with bright simulated diamond accents. Crafted in solid 925 sterling silver with a rhodium finish, this glamorous ruby engagement ring turns a proposal, anniversary or July birthday into a statement she will not stop looking at.

A square-cut showstopper

The princess cut is all crisp corners and fiery sparkle — a modern, confident shape that fills the finger and catches light from every facet. Here it holds a bold, sizeable ruby in a square 8 x 8 mm silhouette, so the color reads rich and dramatic from across a room. It is for the person who wants their ring to be seen, an eye-catching alternative to the traditional diamond solitaire. If that big-color, high-impact look is what you are chasing, you will find it throughout our ruby engagement rings collection.

The genuine lab-grown ruby

The center is a real ruby — a lab-grown ruby is genuine corundum, the same mineral as a mined ruby, grown in a controlled environment rather than the earth. It carries the identical bold red and the identical hardness, which is what makes a stone of this presence possible at a sensible price. The precise princess faceting is engineered to maximize brilliance, giving the ruby a bright, fiery flash. To learn what the gem has symbolized through history, our guide to ruby meaning is a great read, and if July is the occasion, our July birthstone guide is worth a look.

Bright simulated diamond accents

Along the shoulders, simulated diamonds add a crisp flash of white sparkle that plays against the ruby’s fire and makes the red glow even deeper. They are a bright, budget-friendly way to build classic engagement-ring shimmer around a dramatic center stone. Prefer a lab-grown diamond or moissanite accent instead? Message us — most of our designs can be tailored.

Solid sterling silver with a rhodium finish

The ring is crafted in solid 925 sterling silver and finished with a layer of rhodium — the same precious metal used on fine white-gold jewelry. That rhodium finish gives the ring 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 silver ring wear like something far more expensive.

What a ruby symbolizes

The ruby has always been the stone of passion, strength and love — the perfect emblem for a bold, wholehearted commitment. As July’s birthstone it also makes a deeply personal summer-birthday gift. Colored center stones are increasingly the choice for couples who want something with more presence than a colorless diamond; our red engagement rings guide explores the trend.

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 ruby 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. With the ruby’s Mohs 9 hardness, this is a ring made to be worn every day.
