- 5+ years of professional experience in the Mineral trade as a dealer, curator, collector, academic specialist, or commercial expert.
- A strong industry network of Mineral dealers, miners, collectors, and specialist suppliers.

- Strong understanding of pricing, value tiers, authenticity requirements, and best practices for online curation.
- Professional communication skills with experience resolving disputes when needed.
- Good computer literacy and comfort working in a fast-paced digital environment.
