A U.S.-based, family-run mineral business specializing in authentic Chinese specimens — built on forty years of heritage in the mining and mineral trade.
My Mineral Box is co-founded by Maggie Liu and Jack Miller. Each year Maggie spends extended time at mines across China — working directly with miners and lapidary partners to curate specimens you cannot find through standard wholesale channels. Jack runs the operations side and built our industry-leading packing standard. The result is a small catalog of carefully verified pieces, every one chosen by someone who has held it in their hands.
“Crystals are gifts from nature — shaped over millions of years and filled with the quiet wisdom of the Earth.”— Maggie Liu, Co-founder
Asian American entrepreneur with a lifelong fascination for minerals, bringing 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.
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 U.S. or overseas.
At MyMineralBox we prioritize geological accuracy and locality transparency. Every specimen passes a 3-step verification.
How we source and verify Chinese mineral localities →
Specific mine, district, and province data. We avoid generalized labels (e.g. just “China”) when specific locality data is available.
AGTA-aligned disclosure standards. Any heat, irradiation, or repair is explicitly stated in the specimen's technical data.
All photos are color-calibrated to 5500K (Daylight) — the digital representation matches the physical specimen you receive.
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.
Before launching our independent site, we established ourselves on Etsy with thousands of verified sales. Our shop maintains 5-Star Ratings — proof of our long-standing commitment to quality, authenticity, and outstanding packing.
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.
Our research covers key Chinese mining districts including Yaogangxian Mine in Hunan Province, Xuebaoding in Sichuan, and many more.
