Physical Authentication

COA Specialists & Physical Authentication

When photo-based analysis returns an inconclusive result, or when you need formal authentication for high-value artifacts, we recommend consulting with a certified authenticator who can perform hands-on examination.

What physical examination provides

Weight and density analysis - Authentic artifacts have characteristic heft based on material type
Microscopic edge examination - Use-wear patterns, micro-flaking, and edge polish
Patina and weathering assessment - Surface characteristics that develop over centuries
Material sourcing verification - Matching stone type to known regional sources

Finding a specialist

We are building a network of trusted COA (Certificate of Authenticity) partners. In the meantime, here are resources for finding qualified authenticators:
