Our story

The story of Stellini Diamonds

It all started in 2018 when I was looking for an engagement ring for my partner. I never would have imagined back then that it would one day lead to my own jewelry business. Today – six years later – I'm proud to run Stellini Diamonds, a company that does more than just sell rings. We're all about making people happy, trading fairly, and protecting our environment. It's a great feeling to be part of so many beautiful love stories while doing something good.
– Giuliano Stellini, founder of Stellini Diamonds

The idea for Stellini Diamonds was born out of several personal experiences:
I was sold a diamond as VS —a quality grade where inclusions should be difficult to detect under 10x magnification and nearly invisible to the naked eye. However, upon examining the stone, I could clearly see the inclusions.

After a brief investigation, I realized that many jewelers operate with such misjudgments or misleading information—often to the detriment of their customers. After all, who knows the ins and outs of the complex grading guidelines for diamonds? Most people have completely different issues in their daily lives and rely on the salesperson's expertise.

This is exactly where Stellini Diamonds comes in: trust.
We want to be a trustworthy partner with whom you can be sure that everything we tell you is true . Every single diamond we carry is sold exclusively with an official certificate —so you, as our customer, have absolute transparency and security.

Our goal is to introduce you to the complex world of diamonds in a clear and honest way—without hidden compromises or false promises. Because trust is paramount with such a valuable investment.
