ARNOLDI INTERNATIONAL

Arnoldi International is a family-owned gemstone cutting company based in Idar-Oberstein, Germany, with a tradition dating back to 1919. Now led by the third and fourth generations of the Arnoldi family, the company combines more than a century of experience with modern production techniques and a commitment to preserving traditional gemstone-cutting craftsmanship. Its work is guided by close attention to customer requirements, careful sourcing from established trading partners and, where possible, ethically operated mines, and precision in every stage of production.

The company offers a broad selection of fine coloured gemstones, including aquamarine, emerald, tourmaline, garnet, tanzanite, peridot, spinel, sapphire and ruby. Aquamarine is a particular speciality. Arnoldi’s skilled lapidaries cut individual stones, rare specimens and calibrated series, shaping gems as either cabochons or faceted stones. Customers can also explore and order gemstones through the company’s online B2B platform, Gemweb, which provides a view of its collection. Through in-house manufacturing and regular journeys to gemstone-producing regions, Arnoldi selects rough stones and transforms them into finished gems for jewellery businesses worldwide, with quality presented as Made in Germany.
