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

Valoterna was founded by two people with a shared mission: to make gemstones accessible, as they deserve – transparently, expertly, and personally. Maria Stadler is an internationally accredited gemologist who regularly travels to the world's mines and markets. Patrick-Noël Gregor brings his background in private equity: valuation, structure, and market knowledge that extend far beyond traditional gemstone trading.

We focus on natural, untreated, high-quality colored gemstones. We select each gemstone personally, thus taking on the pre-selection and your risk: you can trust that you're getting the best. All gemstones are thoroughly checked and come with certificates from recognized gemological laboratories. Nature in perfection. For you and for the next generation.
