At FineDiam, our lab-grown diamond jewellery collection brings together the brilliance and beauty of certified diamonds with the craftsmanship of our Hatton Garden, London workshop. Every lab-grown diamond we use is IGI or GIA certified, and every piece of jewellery is UK hallmarked by the London Assay Office. Whether you are searching for an engagement ring, a diamond necklace, a tennis bracelet, or a pair of diamond earrings, our lab-grown diamond collection offers extraordinary quality at a more accessible price point.
What Are Lab-Grown Diamonds?
Lab-grown diamonds are created using two primary methods: High Pressure High Temperature (HPHT) and Chemical Vapour Deposition (CVD). Both methods replicate the conditions under which natural diamonds form, producing a diamond that is physically, chemically, and optically identical to a mined stone. Lab-grown diamonds are graded using exactly the same 4Cs — cut, colour, clarity, and carat weight — as natural diamonds, and they are certified by the same independent gemological laboratories, including the IGI (International Gemological Institute) and the GIA (Gemological Institute of America).
Lab-grown diamonds are not to be confused with diamond simulants such as cubic zirconia or moissanite, which are entirely different materials with different optical and physical properties. A lab-grown diamond is a diamond in every meaningful sense of the word.
Why Choose Lab-Grown Diamond Jewellery?
Lab-grown diamonds offer several compelling advantages over mined diamonds without any compromise in quality or beauty.
Exceptional value: Lab-grown diamonds are typically available at a significantly lower price per carat than natural diamonds of equivalent quality, allowing you to choose a larger stone, a higher colour grade, or a more elaborate setting within your budget.
Certified quality: Every lab-grown diamond in our collection is IGI or GIA certified, guaranteeing its cut, colour, clarity, and carat weight to the same standards as natural diamonds.
Identical beauty: Lab-grown diamonds have the same refractive index, the same hardness (10 on the Mohs scale), and the same brilliance and fire as natural diamonds. They are indistinguishable to the naked eye — and to most gemological instruments.
Traceable origin: Lab-grown diamonds have a fully traceable and transparent supply chain, making them a popular choice for those who value ethical sourcing.
Our Lab-Grown Diamond Jewellery Collection
Lab-Grown Diamond Engagement Rings
A lab-grown diamond engagement ring allows you to choose a larger, higher-quality diamond within your budget without any compromise in beauty or certification. Our lab-grown diamond engagement rings are available in a wide range of styles — solitaire, halo, three-stone, and pavé — in white gold, yellow gold, rose gold, and platinum. All diamonds are IGI or GIA certified.
Lab-Grown Diamond Necklaces & Pendants
A lab-grown diamond necklace or pendant offers the same brilliance and beauty as a natural diamond necklace at a more accessible price point. Our diamond necklaces are available in solitaire, halo, and cluster designs in white gold, yellow gold, rose gold, and platinum.
Lab-Grown Diamond Earrings
From classic diamond stud earrings to elegant drop earrings and statement hoops, our lab-grown diamond earring collection offers something beautiful for every occasion. Lab-grown diamond studs are one of the most popular choices — allowing you to choose a larger carat weight within your budget for maximum impact.
Lab-Grown Diamond Tennis Bracelets
A lab-grown diamond tennis bracelet offers the same continuous line of brilliant diamonds as a natural diamond bracelet, at a price point that makes this iconic piece more accessible than ever. Available in white gold, yellow gold, rose gold, and platinum, in a range of total carat weights.
Lab-Grown Diamond Eternity Rings
A lab-grown diamond eternity ring — whether full or half eternity — is one of the most meaningful anniversary and milestone gifts you can give. Our eternity rings are available in round brilliant and princess-cut lab-grown diamonds in white gold, yellow gold, and platinum.
Lab-Grown vs Natural Diamonds – Which Should You Choose?
Both natural and lab-grown diamonds are real diamonds, and both are beautiful. The right choice depends on your priorities. If the rarity and geological history of a natural diamond is important to you, a natural diamond is the right choice. If you want the largest, highest-quality certified diamond within your budget, a lab-grown diamond offers exceptional value. At FineDiam, we offer both options across our collection, and our team is always happy to help you make the right choice for your needs.
