Personal. Reliable. On equal terms.
"Gemstones. As unique as you."

Behind Valoterna are two people with a shared ambition: to make gemstones accessible as they deserve – transparently, expertly, and personally. Maria Stadler is an internationally accredited gemologist, regularly traveling to the mines and markets of the world. Patrick-Noël Gregor brings his background from the private equity sector: valuation, structure, and market knowledge that goes far beyond traditional gemstone trading.

We focus on natural, untreated, high-quality colored gemstones. We select each gemstone using the four-eyes principle, thus taking care of the pre-selection and your risk: you can trust that you are getting the best. All gemstones are multiple-tested and accompanied by reports from recognized gemological laboratories. Nature in perfection. For you and for the next generation.
