Our story
Swiss diamond jewelry with responsibility and style
Sarielia is an exclusive Swiss diamond jewelry brand of InfinityStar GmbH, headquartered in Frauenfeld, Switzerland. Our brand stands for modern luxury, the highest quality, and a clear conviction: true jewelry should not only be beautiful, but also worn with a good conscience.
Our vision
The idea behind Sarielia arose from the desire to make high-quality diamond jewelry accessible online without compromising on ethics, craftsmanship, or transparency. In an industry often characterized by a lack of transparency, we pursue a different approach: honest, clear, and responsible.
Our goal is to create contemporary diamond jewelry that is both aesthetically and morally convincing for people who value quality, origin and meaning.
Experience meets passion
With extensive experience in the international jewelry industry and a passion for meaningful design, Sarielia was founded as a trusted alternative to traditional jewelers. We combine Swiss precision with timeless elegance and modern design – inspired by clean lines, fine details, and enduring aesthetics.
Each piece of jewelry is carefully selected and designed to accompany special moments: engagements, weddings, anniversaries or personal milestones.
Responsibility & Transparency
Responsibility is not a trend for us, but a fundamental principle. That's why we rely on responsibly sourced diamonds and modern manufacturing processes that respect ethical standards. Transparency towards our customers is a matter of course for us – from the selection of materials to pricing.
Sarielia stands for fair luxury that harmonizes quality, design and values.
Swiss quality, designed for the international market
As a Swiss jewelry brand, we place the highest value on precision, reliability, and quality. At the same time, we think internationally: Our collections are aimed at style-conscious customers in Switzerland and Europe who want to buy diamond jewelry online – securely, transparently, and conveniently.
Thanks to modern technology, clear product information and personal service, we create a shopping experience that inspires trust and delights.
