"Authentically sourced from the heart of China's mineral rich provinces."
Welcome to My Mineral Box
Your trusted source for authentic mineral specimens, fine crystals, and collector-grade stones from around the world.
We are Maggie Liu and Jack Miller, co-founders of My Mineral Box — a U.S.-based, family-run mineral business built on passion, integrity, and more than forty years of heritage in the mining and mineral trade.
Our Story & Heritage
Maggie, an Asian American entrepreneur with a lifelong fascination for minerals, brings deep expertise in Asian mineral localities. Her focus is on the unique geology of China.
She specializes in sourcing diverse treasures—from high-quality Chinese mineral specimens to intricate natural mineral carvings—ensuring every piece is selected for its unique beauty and authenticity.
Operations & Logistics
Jack contributes strong business and logistics experience, helping us combine field expertise with modern global operations and professional customer care.
We believe that how a mineral arrives is just as important as the mineral itself. Our packing standard ensures your specimens arrive safely, whether you are in the US or overseas.
Sourcing at the Mines
Each year, Maggie spends extended time at mines across China and other parts of Asia, working directly with miners and lapidary partners to curate the finest mineral specimens at the source.
These field trips ensure that every crystal is selected for authenticity, aesthetic beauty, and geological significance — representing the best of Asia's mineral heritage.

(Specimens)Our Curation & Provenance Standards
At MyMineralBox, we prioritize geological accuracy and locality transparency. Every specimen in our catalog undergoes a strict 3-step verification process.
1. Locality Confirmation
We strictly label specimens with their specific mine, district, and province data. We avoid generalized labels (e.g., just "China") when specific locality data is available.
2. Treatment Disclosure
We adhere to the AGTA guidelines for disclosure. Any treatments (heating, irradiation, or repair) are explicitly stated in the specimen's technical data.
3. Visual Authenticity
All photos are color-calibrated to 5500K (Daylight) to ensure the digital representation matches the physical specimen you receive.
Our Mineral Expertise
With deep knowledge of mineralogy and Asian mineral localities, My Mineral Box publishes in-depth collector guides and locality research to help collectors worldwide make informed decisions.
