About us

When René Arnoldi’s grandfather founded the company Carl Friedrich Arnoldi in the year 1919, he provided the basis for a traditional and highly reputed gemstone-cutting factory in Idar-Oberstein. René Arnoldi, the current owner of ARNOLDI INTERNATIONAL, has been developing his expertise and love of exclusive gemstones for more than 40 years now. No matter whether it is a single stone, a rarity or a series of calibrated stones, whether cut as a cabochon or facetted: Every gemstone receives exclusive attention by our team of highly skilled and experienced gemstone experts. This results in attractive designs with optimally balanced proportions and perfect finish, setting standards for our customers that can only be achieved in our in-house studio.
