      Lab-Grown Diamonds

      What is a lab-grown diamond?

      A lab-grown diamond is just that, a diamond. It consists of carbon atoms with the same crystal structure, chemical composition, and optical and physical properties as a mined diamond.

      A lab-grown diamond is a fantastic feat of technology. First, a diamond seed is placed in a sealed chamber and heated to around 800 degrees Celsius. Next, the chamber is filled with a carbon-rich gas, breaking molecular bonds. Finally, pure carbon adheres to the seed and crystallises, forming a diamond with the same scintillation, flash, fire, and brilliance as earth-extracted diamonds.

      What’s the difference between mined and lab-grown diamonds?

      The only difference between mined and lab-grown diamonds is that a lab-grown diamond is created under controlled conditions. This allows for a more transparent supply chain and reduces carbon footprint.

      Lab-grown diamonds have no nitrogen in the lattice and are classified as Type IIa. Diamonds entirely devoid of impurities are rare, and only 5% of all mined diamonds can compare.

      Are lab-grown diamonds more sustainable?

      For every carat, a mined diamond requires 7300 litres of water and emits 160kg of CO2. This is drastically high compared to just 1 litre of water and 12kg of CO2 for each carat grown in a lab. (Trucost Report 2017). Therefore, creating our jewels exclusively with lab-grown diamonds is a conscious choice. Moreover, all Unsaid diamonds are grown at our lab, ALTR Tech in Surat, India, and are powered with renewable energy.

      Where are Unsaid diamonds grown, and do they come with a certificate?

      All our jewels are designed and crafted at our state-of-the-art facilities in India. In addition, our parent company, Walking Tree, has over 100 years of combined experience in diamond cutting, designing and crafting jewels, a savoir-faire that we have brought to Europe in the form of Unsaid.

      Our diamonds are grown in our Surat, India lab before being taken to our Mumbai factory, where we have been cutting diamonds for three generations. Our local artisans bring decades of knowledge and passion to every Unsaid diamond, pushing boundaries yearly.

      Every round diamond weighing 0.5 carats or more comes with a diamond certificate with H+ colour and VS+ quality. The certificate is issued by the International Gemological Institute (IGI), an independent laboratory and official organisation. This veritable identity card indicates your diamond's composition of the 4Cs while providing supplementary information.

      What are the 4Cs?

      The 4Cs—colour, clarity, cut, and carat weight—are the globally accepted standards for assessing the quality of a diamond.

      Colour: refers to the natural tint inherent in white diamonds. Most white diamonds have a slight shade of yellow, and diamonds come in various colours.

      Cut: refers to how a diamond’s facets interact with light and are the only criteria that depend entirely on human hands. The cut enhances all of a diamond's qualities and reveals the perfect balance between brilliance, fire, and scintillation.

      Clarity: refers to the number, size, position, and colour of the inclusions visible in the stone under a 10x magnifying glass. The more inclusions there are, the less clarity and value of the stone since inclusions affect the diamond’s ability to reflect light.

      Carat: refers to the weight of a diamond, not the size. One carat equals 0.20 grams, which has been an international standard unit of measurement since 1907. The word "carat" comes from the seeds of the carob tree, used in antiquity to measure the weight of a diamond.

      Product Information and Care

      Does my jewellery come with a certificate?

      All Unsaid jewels come with a jewellery certificate which details the specifications of the jewel. To avoid counterfeits, we strongly suggest you always purchase your jewellery from an Unsaid store or authorised retailer.

      Every round diamond weighing 0.5 carats or more comes with a diamond certificate with H+ colour and VS+ quality. The International Gemological Institute (IGI), an independent laboratory and official organisation, issues each Unsaid certificate.

      How do I choose the right size for my Unsaid jewellery?

      If you are unsure about sizing, please look at our Sizing Guide before placing your order.

      Our expert team is also available to give advice. You can email us at hello@unsaid.com, call +33 6 95 11 99 76 or book a virtual appointment Tuesdays to Saturdays, 10 am - 5 pm.

      Why should I have my Unsaid jewellery serviced?

      Regular maintenance is the best way to ensure the longevity of your precious jewels. In everyday use, your jewellery might be subject to stress, such as bumps, scratches, UV radiation, dust, sweat, and fluctuations in temperature. For this reason, we recommend you have your jewellery cleaned and serviced every three years by bringing it to one of our stores or an authorised distributor.

      Unsaid offers a range of repair services for any products purchased in our stores, from unsaid.com, and via authorised distributors. For repairs, deposit your Unsaid jewellery in our after-sale services (care services) in our stores where we will systematically repair them in our workshops by our artisans.

      The “Our store” section on unsaid.com allows you to locate your nearest store. If you do not have an Unsaid store near you or you cannot travel, please contact our Customer Service team by email at hello@unsaid.com.

      How do I take care of my jewellery at home?

      Handle your jewellery carefully to keep its beauty and brilliance. Protect your jewellery from being scratched against hard surfaces and sudden movements that could cause damage to the stone or setting. Store your jewels in its Unsaid box to avoid scratching and entangling.

      We recommend removing all jewellery when doing household chores as repeated contact with detergents and bleach can damage precious metals, also before engaging in sports or getting in contact with water.

      To clean a stone or a diamond pavé, use a mild non-abrasive cleaner and a soft toothbrush under hot water to gently remove dirt without damaging the jewellery.
