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.

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 crystallizes, forming a diamond with the same scintillation, flash, fire, and brilliance as earth-extracted diamonds.

The only difference between mined and lab-grown diamonds is that lab-grown diamonds are 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.

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.

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

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

Color refers to the natural tint inherent in white diamonds. Most white diamonds have a slight shade of yellow and come in various colors.

Cut refers to how a diamond's facets interact with light. It is the only criterion that depends entirely on human hands. The cut enhances a diamond's qualities and perfectly balances brilliance, fire, and scintillation.

Clarity refers to the number, size, position, and color of the inclusions visible in the stone under a 10x magnifying glass. The more inclusions, 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 its size. One carat equals 0.20 grams, an international standard unit of measurement since 1907. The word "carat" comes from the seeds of the carob tree, which were used in antiquity to measure the weight of a diamond.

Regular maintenance is the best way to ensure the longevity of your precious jewels. In everyday use, your jewelry 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 jewelry cleaned and serviced annually by bringing it to one of our stores or an authorized distributor.

Unsaid offers repair services for products purchased in our stores from unsaid.com and via authorized distributors. For repairs, deposit your Unsaid jewelry 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 cannot travel, please email our Customer Service team at hello@unsaid.com.

Handle your jewelry carefully to maintain its beauty and brilliance. Protect it from scratches against hard surfaces and sudden movements that could damage the stone or setting. Store your jewelry in its Unsaid box to avoid scratching and entangling.

We recommend removing all jewelry when doing household chores, as repeated contact with detergents and bleach can damage precious metals. This is also true before engaging in sports or 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 jewelry.
