Diamonds are the only gemstone composed of a single element — pure carbon, crystallised under extreme pressure and heat deep within the earth over billions of years. This singular composition gives diamonds their unmatched hardness, brilliance, and fire.
The value of a diamond is determined by the 4Cs: cut, colour, clarity, and carat weight. Of these, cut has the greatest impact on a diamond's visual beauty — a well-cut diamond returns light through the top of the stone, creating the sparkle that makes diamonds so captivating.
At MOH London, we offer both natural and lab-grown diamonds. Lab-grown diamonds are physically, chemically, and optically identical to natural diamonds, certified by the same laboratories (GIA, IGI), and offer exceptional value — typically 60-80% less than natural equivalents.
As the hardest gemstone (10 Mohs), diamonds are perfect for every type of jewellery, especially engagement rings worn daily. Visit our Hatton Garden showroom to view diamonds across the 4Cs spectrum and find the perfect stone for your budget.
The April birthstone is the diamond — the hardest natural substance on earth, symbolising eternal love, strength, and purity. Diamonds are the most popular gemstone for engagement rings worldwide.
Yes — lab-grown diamonds are real diamonds. They are physically, chemically, and optically identical to mined diamonds. The only difference is their origin: grown in a laboratory in weeks rather than formed in the earth over billions of years.
Diamond stud earrings are the most popular April birthday gift — timeless, versatile, and suitable for everyday wear. A pair of 0.50ct total weight studs in 18k white gold is a beautiful choice. Diamond pendants and tennis bracelets are also excellent options.
