HC Arnoldi

Welcome to Kirschweiler!

Experience grown over generations

We have been working with colored gemstones for over 100 years. Over generations, close and long-standing relationships have been forged with our partners and suppliers. We accompany many of our rough stones from their origin, through selection and purchasing, to cutting in our own lapidary.

Our team of around 35 employees combines experience in the gemstone trade with expert craftsmanship. We provide personal consultation to jewelers, goldsmiths, designers, and jewelry manufacturers regarding our product range, custom cuts, and current developments in the colored gemstone market.

From our location in Idar-Oberstein, we work with customers in Germany, Europe, Asia, and the USA. Personally on-site, at international trade fairs and sales trips, as well as via our online shop.

We are very grateful for the long-standing trust of our customers and partners
