Reimagining Fine Jewellery with Lab Diamonds & Ethical Gems

Lab-grown diamonds are becoming the preferred choice for conscious shoppers in the UK. With the same physical, chemical, and visual properties as natural diamonds, they offer identical brilliance and durability, but without the ethical or environmental cost. At Ouros Jewels UK, we specialise exclusively in lab-created diamonds that reflect modern values and timeless elegance.

Our wide inventory includes a wide range of certified stones, tested and authenticated by world-renowned gemological laboratories, including the International Gemological Institute (IGI), the Gemological Institute of America (GIA), Gem Certification & Assurance Lab (GCAL), Solitaire Gemmological Laboratories (SGL), and the European Gemological Laboratory (EGL). This ensures every stone meets the highest standards in quality, origin, and precision.

Beyond diamonds, our collection also celebrates the beauty of colour. You’ll find lab-grown coloured diamonds and gemstones in nearly every shade, from blush pinks and ocean blues to emeralds and warm yellows. Each piece can be customised to reflect your personality or align with symbolic meanings, whether you're choosing a birthstone, zodiac gem, or simply a crystal with your favourite hue.

Ouros Jewels UK is committed to creating jewellery that respects the planet and its people. Our diamonds are conflict-free, cruelty-free, and grown using technology that significantly reduces environmental impact. Every piece is a reflection of your values, your style, and your story.

Custom Diamond Shapes – Ouros Jewels UK Signature Craft

We specialise in made-to-order diamond cuts that go beyond the ordinary, each one thoughtfully shaped to carry meaning. From antique shapes to never-seen-before modern 8X cut diamonds, our custom-cut lab-grown diamonds are designed to reflect the individuality of your story.

Whether it’s a heart-flushed butterfly shape, a symbolic initial cut, or a brilliant 8x round cut diamond, we create jewellery where design becomes identity. These aren’t just unique cuts, they’re personal emblems, crafted exclusively for those who see jewellery as more than adornment.

At Ouros Jewels UK, every custom shape is an emotional blueprint created not just with tools, but with intention.

Vintage Beauty – The Allure of Old Mine Cut Diamonds

Step into a world where every facet tells a tale. Our vintage-inspired collection celebrates the romance of the past through Old Mine Cut diamonds, including rare shapes like the Old Mine Cushion Diamond and the elongated Old Mine Moval Diamond.  A classic gems that echo the elegance of the Georgian and Victorian eras.
