Princess Cut Diamond Engagement Rings | Hatton Garden, London

Sharp corners. Precise geometry. Extraordinary sparkle. The princess cut is the second most popular diamond shape in the world — and it’s easy to see why. Its square silhouette and brilliant faceting deliver fire and scintillation that rivals even the classic round cut, while its clean, contemporary lines give it a distinctly modern edge.

At FineDiam, every princess cut diamond engagement ring is curated in Hatton Garden, London — UK hallmarked and delivered in a luxury gift box. Both lab grown and natural diamond options are available across the collection.

Why Choose a Princess Cut Diamond?

• Exceptional brilliance — princess cut diamonds feature up to 76 facets, delivering intense fire and scintillation from every angle
• Modern and geometric — the square shape offers a sleek, contemporary look that stands apart from traditional round cuts
• Larger face-up appearance — princess cuts often appear larger than round diamonds of the same carat weight due to their square surface area
• Versatile setting compatibility — works beautifully with solitaire, halo, channel-set and three-stone settings
• Timeless yet distinctive — first popularised in the 1970s, the princess cut has become a modern classic that never dates

Our Princess Cut Diamond Engagement Ring Styles

One princess cut diamond. One perfect band. The solitaire lets the stone’s sharp geometry and brilliant sparkle speak entirely for itself. Available in platinum, white gold, yellow gold and rose gold.

Milgrain edging and intricate detailing fused with the precision of a princess cut — old-world romance meets modern geometry.

Lab Grown vs Natural Princess Cut Diamonds

Both lab grown and natural princess cut diamonds are real diamonds — chemically identical, equally brilliant, and set in the same precious metals. Lab grown diamonds allow you to choose a larger stone or higher quality grade for your budget. Natural diamonds carry traditional rarity and heritage value. Diamond details and any grading reports are listed on each individual product page.
