Among the most-loved pieces in our collection is the round engagement ring. Timeless and brilliantly cut, the round brilliant’s balanced sparkle flatters every hand—crafted to be worn and admired for a lifetime.

What Makes Round Engagement Rings So Special?

The round brilliant is engineered for light—its facet pattern maximises fire and scintillation, delivering classic sparkle in any lighting. The shape pairs effortlessly with every setting style and wedding band, making it the most versatile choice.

At House of Diamonds, we refine proportions and head height so your round centre stone sits comfortably, looks balanced from every angle, and shines in everyday wear.

The Craftsmanship Behind a Round Solitaire

Precision prongs, clean symmetry, and thoughtful head design matter. Whether you choose a 4-prong (open, minimal) or 6-prong (secure, slightly rounder outline), our setters shape and polish each claw for a smooth, secure finish that lets the diamond take centre stage.

Explore Our Range

Discover classic solitaires, pavé-band rounds, cathedral shoulders, hidden halos, halos, and three-stone designs. Choose natural or lab-grown diamonds, your metal (18K yellow, white, rose gold or platinum), and band styles from delicate to sturdy for daily wear.

Why Choose a Round Diamond?

A round diamond delivers the most consistent brilliance and easy styling. It stacks beautifully with straight, curved, or pavé wedding bands and looks refined at every carat size—from petite to statement.

FAQ: Round Engagement Rings

Why is the round brilliant so popular?

Its facet pattern is optimised for brightness and fire, giving consistent sparkle in most lighting and suiting every setting style.

4-prong vs 6-prong—what’s the difference?

4-prong shows more of the diamond and looks slightly squarer; 6-prong adds security and a softer, rounder outline. Both are durable when well made.

Which band width should I choose?

1.8–2.2 mm for a delicate look, 2.3–2.6 mm for balance, 2.7 mm+ for a sturdier feel. We’ll size it to your hand and centre stone.

Does a halo or hidden halo make a round look larger?

Yes—both add visual presence. A classic halo enlarges the top view; a hidden halo keeps a clean solitaire look with side sparkle.

Natural vs lab-grown round diamonds—any visual difference?

Visually, both perform beautifully. We focus on cut quality, symmetry, and polish so your diamond looks its best in real life.

Can my round solitaire be resized later?

Usually within 1–2 sizes depending on the band. Plain bands are especially resize-friendly; full-eternity pavé is not.
