It all started in 2018 when I was looking for an engagement ring for my partner. Back then, I would never have thought that it would become my own jewelry company. Today - six years later - I am proud to run Stellini Diamonds, a company that does more than just sell rings. We are all about treating people fairly. It's a great feeling to be part of so many beautiful love stories and do something good at the same time.

The idea for Stellini Diamonds came from personal experience. I had bought an engagement ring for my future wife that was marked as VS quality - inclusions should hardly be visible under 10x magnification. But even with the naked eye they were clearly visible.
During my research, I discovered that many jewelers work with misjudgements or misleading information, often to the detriment of the customer. After all, who knows the details of the complex valuation guidelines for diamonds? Most people rely on the expertise of the salesperson.
We want to be a reliable partner that you can trust 100%. Every diamond in our range is sold exclusively with an official certificate and selected by me, for absolute transparency and security.
Our aim is to introduce you to the world of diamonds honestly, comprehensibly and without false promises. Because with such a valuable investment, one thing counts above all: trust.
Made in Switzerland. At Stellini, quality is the most important thing. That's why we only use high-quality precious metals to create unique pieces of jewelry that you will enjoy for a long time - and all made in Switzerland.
We also offer laboratory diamonds, which are diamonds produced in a laboratory and are an excellent alternative to mined diamonds. They help to reduce the environmental footprint while offering excellent quality at a lower cost.
We select our diamonds with the utmost care and sophistication to ensure that only the most beautiful stones are used in our jewelry. This enables us to meet the highest demands of our customers.
We want everyone to feel well informed when choosing a ring. With us, you can find out openly and honestly what options are available, without hidden costs or uncertain sources.
Today, we are one of the best-known providers of engagement rings with laboratory diamonds that are processed fairly and responsibly.
More than 500 couples in Switzerland have already placed their trust in us and had their special pieces of jewelry made by us.
