INTERGEM 2023: New exhibitors set accents – ticket sales started

Idar-Oberstein. Additionally to the well-known and highly reputated companies from the region such as Groh + Ripp, Karl Faller, HC Arnoldi we are welcoming interesting and exciting new exhibitors at INTERGEM 2023.

Knowledge and expertise about the still relatively unknown element osmium, the rarest precious metal of the world, will be provided by the Osmium Institute and Oslery GmbH. It has only be possible to produce flat crystalline osmium in Switzerland in a controlled manner since 2014. The sparkling surfaces are perfect for the production of jewellery and watches. In the USA crystalline osmium is also called the sunshine element because of its special reflection. Brands like Ulysee Nardin, Hublot or Czapek have already produced watches with the last of the precious metals. Due to its density (the highest of all elements) and its distinctive crystal structure, the precious metal in its crystalline form is absolutely forgery-proof. Its rarity and its wonderful blue-silver shine also makes osmium an interesting future investment that can also be worn as beautiful jewellery. Scarlett Clauss, Managing Director of Oslery GmbH and Vice Director of the Osmium Institute, will be available personally at INTERGEM 2023. Lectures on this special topic will be given at the stand in the foyer on Saturday at 2 pm and on Sunday at 11 am.
