HC Arnoldi, a family-run company in the Idar-Oberstein region, is one of the leading gemstone manufacturers and traders. With a tradition stretching back over a hundred years, we shape the jewelry industry with high-quality colored gemstones. Our many years of experience combine expertise and innovative strength to produce gemstones of the highest quality.

Our Path to Perfection

For over four generations, we have accompanied gemstones from their origin to our customers worldwide. This direct path enables us to monitor and ensure the quality of each individual gemstone. The rough gemstones are exclusively sourced by the experienced hands of Hubert Arnoldi and his son Carl-Philip.

Craftsmanship and Innovation

Our highly qualified specialists in the cutting shop apply their craftsmanship and experience to the processing of each gemstone. Each stone is carefully cut, polished and finished by hand to bring out its natural beauty. Our sales-team presents the finished gemstones to national and international customers and is also represented at over 9 international trade fairs. The back-office team takes care of communication, shipping and all logistical tasks relating to the gemstones. Since 2020, some of the gemstones cut by HC Arnoldi have been available for purchase in our subsidiary, the B2B online shop gemhype.com.

Variety of Gemstones

From classic-colored gemstones such as aquamarines, tourmalines, tsavorites, and spinels to rare Paraiba tourmalines, we offer a wide selection of gemstones in various colors, shapes, and sizes. Our range includes both unique gemstones and calibrated gemstones. The design-team puts together perfectly matching gemstone sets, such as necklaces, bracelets, or sets of earrings, rings, and necklaces.
