Natural diamonds have been celebrated for their extraordinary beauty and unique origin story for centuries. These precious gemstones have become the ultimate symbol of timeless elegance and value, making them the most sought-after stones in luxury jewellery.
This guide takes a closer look at the incredible journey of natural diamonds—from their formation deep in the Earth to their role in creating unforgettable pieces of jewellery that mark life's most significant moments.
What are Natural Diamonds, and How are they Formed?
A natural diamond is a gemstone created through a fascinating natural process that spans billions of years. Here's how the process happens, step by step.
Carbon Deep in the Earth: It all starts about 150–200 kilometres below the Earth's surface. Carbon atoms in the Earth's mantle endure extremely high temperatures (over 1,000°C) and immense pressure (more than 725,000 pounds per square inch).
Crystallisation Under Pressure: These conditions force carbon atoms to align and bond, forming a strong and rigid crystal lattice structure. This structure is what gives diamonds their famous hardness and sparkle.
Billions of Years of Formation: The carbon remains in this high-pressure, high-temperature environment for billions of years, slowly transforming into diamonds over time.
Brought to the Surface by Volcanic Eruptions: The diamonds are carried closer to the Earth's surface through volcanic eruptions. These eruptions create igneous rocks, like kimberlite and lamproite, where diamonds appear.
Discovery and Mining: Over time, these rocks erode, leaving behind diamond deposits in rivers, streams, or underground. Miners then uncover these natural gems, bringing them to light for the first time in billions of years.
The Journey from Diamond to Jewellery
After miners unearth a diamond, it begins to transform under the hands of skilled craftsmen, who cut and polish each stone to reveal its brilliance and character. Since each stone forms differently deep within the Earth, no two are exactly alike—which is why they hold their value even when other gems flood the market.
We rigorously test every diamond in our 1899 Collection using the GIA iD100—an advanced technology that ensures 100% accuracy in detecting synthetic diamonds and simulants. As the first jeweller in New Zealand to adopt this technology, we provide complete assurance of each diamond's genuine origin, giving you confidence in every piece you choose.
The Versatility of Genuine Diamond Jewellery
Today, natural diamonds stand as the cornerstone of fine jewellery. Whether celebrating everlasting love with a diamond wedding ring or adding a subtle touch of luxury to your daily routine, these gemstones blend tradition with modern style.
Engagement Rings: A Symbol of Forever
Few things symbolise 'forever' like a diamond engagement ring. It beautifully represents the unbreakable bond of marriage. This tradition dates back centuries, with the first recorded diamond engagement ring presented in 1477 by Archduke Maximilian of Austria to Mary of Burgundy. Since then, diamond rings have become deeply woven into the fabric of romance and matrimony across cultures.
At Walker & Hall, we carry this tradition forward with our collection of engagement rings. We thoughtfully design each cut, setting, and style to reflect your unique love story. The classic solitaire showcases a single diamond for timeless simplicity, while our halo designs surround the centre stone with smaller ones for extra sparkle. For those drawn to deeper meaning, our trilogy rings weave a story of your journey together through three brilliant stones, representing the beauty of your shared past, present, and future.
The round brilliant cut remains a favourite, offering maximum shimmer and elegance. Other cuts, including oval, princess, and cushion, offer a chance to express individuality and style.
Statement Pieces for Dazzling Confidence
Occasions like weddings, anniversaries, and birthdays also call for jewellery that makes an unforgettable impression. Genuine diamond statement pieces capture attention and radiate confidence during life's most special moments. A diamond necklace draped gracefully around the neck adds radiance to any ensemble, while an elegant bracelet effortlessly complements both formal attire and chic evening wear.
Everyday Accessories that Bring Subtle Luxury
While statement pieces command attention at special events, diamonds also add an element of refined luxury to everyday wear. A pair of glittering diamond earrings or a sparkling pendant can transform the most casual outfit, adding the perfect level of shine. These versatile pieces transition seamlessly from morning meetings to evening dinners. Consider them your daily companions in style.
