Stellini Diamonds: Discover timeless diamond engagement rings in Zurich

Our jewelry is made of either natural or laboratory diamonds, 18k real gold and excellent quality - manufactured in Switzerland. The precious gemstones sparkle with responsibility and secure brilliant values for your future, because for us it is not only the cut that counts, but also the origin - aesthetics meets ethics. Visit our diamond atelier in Zurich to get exactly the advice and expertise you are looking for - every step is personally accompanied and explained by our experts. Thanks to years of experience in the diamond trade and our own high standards of diamond purity, you will receive the highest quality without compromise. Every piece of jewelry in our diamond atelier in Zurich and in our online store is unique, created from high-quality precious metals, natural diamonds or laboratory diamonds. In contrast to natural diamonds, laboratory diamonds are not extracted in mines but are cultivated in laboratories using special procedures. They excel in the highest quality with ethics, sustainability and excellent value for money. Only the most beautiful, purest diamonds are processed into unique pieces of diamond jewelry at Stellini Diamonds.

We not only promise you the highest standards, we guarantee you absolute authenticity and tested quality! Whether diamond rings, earrings or diamond necklaces - to ensure independent certification, each of our laboratory diamonds is tested and certified by an IGI gemological expert. The IGI certification proves the authenticity of the diamond and that its origin can be traced transparently. It documents the color, cut, carat weight and purity of the diamond. Just as an invisible signature marks a work of art, a fine laser engraving ensures that the diamond is unmistakable and clearly identifiable. To do this, a very fine, precise laser beam marks the diamond with a report number to guarantee its origin and certification. This inscription is invisible to the naked eye and can only be seen with a jeweler's loupe.

We adhere to extensive, complex guidelines to ensure complete transparency along the entire value chain. The clarity of every diamond is scrutinized by our diamond expert Giuliano Stellini and tested according to the 4C characteristics: Cut, Color, Clarity and Carat. Cut is the cut and determines the brilliance of the stone. The color (Color) is determined between perfectly colorless (D) and slightly yellowish (Z). Clarity is the purity and evaluates inclusions, i.e. tiny flaws inside the diamond. And last but not least: the carat weight of the stone. Giuliano Stellini records the quality characteristics of each stone - you can rely on transparency and clarity down to the last carat. Stellini Diamonds uses at least 18k real gold and only diamonds in the colors D-F and VS for its unique pieces of jewelry. The diamonds only receive the rating "flawless" if our expert cannot detect any inclusions or blemishes under tenfold magnification.

We consciously select sustainable materials so that our diamond jewelry leaves a good feeling - for the person who wears it and for everyone involved in its creation. We use hand-picked natural diamonds and specially cultivated laboratory diamonds of the highest quality - defined by their aesthetic appeal and the sustainable way in which they are produced. From the origin to the unique piece of jewelry, all aspects are carefully considered. This is our understanding of true luxury, which can be experienced both in our diamond atelier in Zurich and here in our online store. Our diamond jewelry is 100% made in Switzerland and the entire, complex value chain is transparent and traceable. Our promise is: real diamonds and true words.
