Hubert Arnoldi

For more than five decades, Hubert Arnoldi’s passion and expertise have been dedicated to colored gemstones. His keen eye for quality begins with the rough stone. He evaluates and purchases selected raw materials and oversees their journey until they become finished, cut gemstones.

To this day, he remains a vital part of the cutting process. Together with his son, Carl Philip, he determines the initial shape of the rough stone, thereby deciding on a crucial step for the subsequent cut. In doing so, he combines decades of experience with a profound understanding of color, proportions, and the potential of each individual gemstone.

As the third generation of the Arnoldi family, Hubert Arnoldi continues the tradition established by C. F. Arnoldi. His experience, his trained eye, and above all his enthusiasm for extraordinary colored gemstones continue to shape HC Arnoldi to this day.

Carl-Philip Arnoldi

A passion for gemstones has been with Carl Philip Arnoldi since his childhood. From an early age, he developed a special interest in the craft of lapidary and the varying properties of colored gemstones. With his training as a gemstone cutter, he ultimately turned this passion into his profession.

Following this, he studied medium-sized enterprise management and remained closely connected to the family business during that time. Whenever his studies allowed, he worked in the company, deepening his practical experience. After graduating, he joined the company full-time.

Today, Carl Philip combines technical knowledge with a keen sense for rough stones and their potential. Together with his father Hubert, he evaluates and purchases raw material and determines the initial shape of the stones. At the same time, as the fourth generation, he brings new perspectives to the company and continues to develop HC Arnoldi together with his family.

Isaline Arnoldi

Isaline Arnoldi’s journey into the family business began from a different perspective. After completing her studies in business psychology and a master’s degree in media and communication management, she focused intensely on the digitalization of the gemstone trade for her master’s thesis. The concept she developed for a B2B online shop eventually led to the creation of gemhype.com together with her brother, Carl Philip.

With the founding of gemhype.com, Isaline also joined the family business, HC Arnoldi, bringing new momentum to the company's further development. Today, her primary focus areas are marketing, human resources, and organization.

Together with Carl Philip, she represents the fourth generation of the Arnoldi family, bridging the established tradition of the family business with new ideas and a modern strategic direction.
