Our Diamonds

Choosing a diamond should feel exciting, not overwhelming. At Pruden and Smith, we take the stress out of the process by doing the hard work for you.

Every engagement ring comes with a carefully preselected diamond, whether you choose a sustainable lab-grown stone or a conflict-free natural diamond. Each one is chosen by our in-house gemologists for its beauty, brilliance, and integrity. Here’s how we do it.

Different Journeys, Same Brilliance

We offer two diamond paths, each chosen to the same high standard of beauty and performance.

Lab-Grown Diamonds
Every lab-grown diamond we offer is IGI certified, graded D Colour and VS1 Clarity, with Excellent Cut, Polish, and Symmetry. Ethically created and identical to natural diamonds, they offer exceptional value without compromise.

Natural Diamonds
Each of our natural diamonds is GIA certified, graded F Colour and VS2 Clarity, and also selected for Excellent Cut, Polish, and Symmetry. Every stone is conflict-free and chosen for its natural brilliance and timeless beauty.

Handpicked with Expertise. Certified by the World’s Leading Labs.

Every diamond we offer is fully certified by the most respected grading laboratories in the world, so you can choose with complete confidence.

Our lab-grown diamonds are certified by IGI and graded D Colour, VS1 Clarity. They’re beautifully white, with no imperfections visible to the naked eye.

Our natural diamonds are certified by GIA and graded F Colour, VS2 Clarity, chosen to meet the same high standards of beauty and brilliance.

All diamonds are carefully selected for their Excellent Cut, Polish, and Symmetry, ensuring maximum sparkle and light return.

Our in-house gemologists review every detail and provide full certification paperwork with your ring, so you know exactly what you’re getting.

Diamond Facts vs Fiction

Lab-grown diamonds are physically, chemically, and visually identical to mined diamonds. They offer the same brilliance, sparkle, and durability.

They’re also widely considered the more sustainable and ethical choice, with a lower environmental impact than traditionally mined stones.

While diamonds have often been marketed as long-term investments, the reality is that unless you’re purchasing an exceptionally rare stone, both natural and lab-grown diamonds hold similar long-term value. Much of the perceived difference has been shaped by decades of clever marketing.

Our philosophy is simple. Choose the diamond that suits your values, your budget, and your style, with complete confidence and no compromise.

Lab-grown diamonds can cost up to four times less than their natural counterparts, giving you more sparkle for your spend.

Understanding the 4Cs – Without the Overwhelm

Choosing a diamond can feel daunting, especially when faced with endless filters, charts, and grading reports.

That’s why we’ve done the work for you.

Every diamond we offer has been handpicked by our expert gemologists using the industry’s gold standard, the 4Cs: cut, colour, clarity, and carat weight. We’ve set a clear benchmark of quality across both lab-grown and natural diamonds, so you’re always choosing from the best.

It’s all the brilliance, without the stress, because when you’re buying something this meaningful, you shouldn’t have to second-guess it.

Cut, Ratio & Design

Beyond the 4Cs, the proportions of a diamond, known as its ratio, play a vital role in how it looks once set. A beautifully cut stone should feel balanced within its setting, enhancing the design rather than overpowering it.

For every engagement ring in our collection, our designers and gemologists have selected diamonds with ratios that suit each design perfectly, whether that’s a round, oval, emerald, or pear shape.

If you’re commissioning a bespoke ring, you can work one-to-one with our designers to explore alternative shapes or proportions. Together, we’ll find a stone that feels just right for you and your ring.
