Full-Seed-to-Polished-Stone Provider
We pride ourselves on being one of the few companies in the diamond industry that oversees the entire process—from the very first seed to the final polished stone. This unique capability allows us to maintain unmatched precision and quality control at every stage of production.
Our journey begins in Osaka, Japan, where cutting-edge technology and generations of expertise come together to grow diamond seeds under the strictest quality standards. These seeds are transformed into brilliant lab-grown diamonds, embodying the renowned craftsmanship and attention to detail that Japan is celebrated for.
Through close collaboration with our polishing partners, we ensure that every diamond achieves the perfect cut and clarity, meeting the highest standards of brilliance. Once polished, our diamonds are distributed globally through Antwerp, the world’s premier diamond hub. This strategic location enables us to connect with jewelers and retailers across Europe and beyond, ensuring seamless delivery and exceptional service.
By managing this full-cycle production and distribution process, we guarantee not only the quality of our diamonds but also the ethical and sustainable practices that define our brand. At every step, SFD Antwerp delivers diamonds that reflect our commitment to excellence, innovation, and sustainability—diamonds that are as flawless in their origin as they are in their beauty.
