An antique stone, responsibly sourced.

A round diamond with a rich champagne hue, presenting a delightful balance between warmth and brilliance. The colour exhibits a blend of C5 and C6 shades, settling into a mid-tone champagne with subtle golden undertones. The hue deepens slightly around the perimeter, while the centre offers a consistent, inviting warmth. Light catches well across the surface, creating a soft, warm glow rather than sharp flashes. The angled facets reflect gentle, muted highlights, enhancing the stone's understated elegance. Several inclusions are noticeable to the unaided eye, particularly concentrated near the girdle, giving the stone a natural and earthy character. Measuring 5.83 by 5.87mm, it faces up true to its 1.00ct weight, with a decent depth of 4.19mm that supports its presence.

Please be aware that photography and video cannot fully capture this stone. Our lightbox images are taken under artificial light, which can flatten a diamond's brilliance and hide the fire that shows in the hand. Video taken in natural light does the opposite, often reading cooler and darker than the stone appears in the hand. The truest impression sits between the two, so we recommend viewing both. Better still, view the stone in person, through an in-store consultation or our Gemstone Home Trial.

Why Choose a Natural Diamond

Natural modern diamonds are chosen for their clarity, strength and enduring symbolism. Formed deep within the earth over immense time, they carry a sense of permanence that suits engagement rings, wedding jewellery and future heirlooms. With contemporary cutting, a natural diamond can feel both timeless and precise: a classic choice with a modern sense of light.

Timeless Origin: A natural diamond is formed by the earth, giving it a sense of age, rarity and permanence that many people still find deeply meaningful.

Modern Brilliance: Contemporary diamond cutting is designed to emphasise brightness, symmetry and precise light return, especially in well-cut stones.

Everyday Durability: Diamond is the hardest natural gemstone, making it very well suited to engagement rings and other jewellery intended for regular wear.

Wide Design Flexibility: Natural modern diamonds are available in many shapes, sizes and qualities, making them suitable for classic solitaires, trilogy rings, halos, clusters and custom designs.

Natural Diamond FAQs

Q: What is a natural modern diamond?

A: A natural modern diamond is an earth-formed diamond cut in a contemporary style. This includes popular shapes such as round brilliant, oval, pear, emerald, radiant, cushion, marquise and princess cut diamonds. These stones are usually cut for brightness, symmetry and a refined face-up appearance.

Q: How is a modern diamond different from an antique diamond?

A: Modern diamonds are generally cut using contemporary proportions and equipment, with more emphasis on brightness, symmetry and precision. Antique and vintage diamonds were cut in earlier periods or older styles, often giving them broader flashes of light, softer patterns and more individual character.

Q: Are natural diamonds suitable for everyday jewellery?

A: Yes. Diamond is the hardest natural gemstone and is very well suited to everyday wear when it is chosen carefully and set securely. As with all fine jewellery, the setting design, stone shape and wear habits still matter.

Q: Do natural modern diamonds come with grading reports?

A: Many natural diamonds are available with independent grading reports, especially larger or higher-value stones. A report can help clarify details such as carat weight, colour, clarity, cut quality and measurements, but we also assess how the diamond looks in real life and how suitable it is for the intended design.
