About Us
JSS Gem & Diamond Mining’ Board of Directors and leadership commit to a high standard of corporate governance to earn the trust of our shareholders and other stakeholders consistently. We follow leading policies and practices, which are regularly assessed to ensure governance objectives are met.
Julie Shaheen Sprague
Founder
At JSS Gem & Diamond , diamond mining is a careful balance of geology, science, stewardship, and respect for the land. Every crystal, whether a Herkimer diamond quartz or a natural diamond, has a story that begins hundreds of millions of years beneath the Earth’s surface.
Ethical Supply & Transparency
Ethical supply means knowing where your stones come from, how they were mined, and who benefits from the process.
- At JSS Gem & Diamond Mining is conducted on legally owned and responsibly managed land
- Environmental disturbance is minimized through careful planning and restoration
- Operations comply with internationally recognized reporting and disclosure standards
- Full transparency is maintained from mine to market
Our long-term geological programs, resource statements, and technical reporting are designed to protect both the land and the integrity of the stones we produce, ensuring customers receive authentic, responsibly sourced treasures.
A Hands-On Mining Experience
In addition to commercial mining, we offer guided wilderness dig experiences for guests who want to connect directly with the Earth’s history. Visitors receive an educational introduction to geology, crystal formation, and mining techniques before exploring our forested dig areas. With expert guidance, guests gain a deeper appreciation for the patience, skill, and science behind every discovery.
Geological Study & Mapping
Mining begins long before any material is removed. Geological surveys, petrographic studies, micro-analysis, and 3D modeling are used to understand the structure of the deposit, identify crystal-bearing zones, and predict where the highest-quality specimens are likely to occur.
Exploration & Drilling
Core drilling programs allow geologists to extract cylindrical samples of rock from below the surface. These samples are studied to assess crystal distribution, size frequency, grade, and value. This scientific approach improves accuracy, minimizes waste, and reduces environmental impact.
Selective Extraction
Rather than mass excavation, our operations focus on selective, controlled extraction. Material is carefully removed and examined to preserve crystal integrity, especially critical for rare forms such as black-stemmed scepters, gem barbells, and hydrocarbon-included “black diamond” quartz.
From Earth to You
Whether you are a collector, investor, jeweler, or adventurer, every stone from JSS Gem & Diamond Mining Supply represents:
• Millions to billions of years of natural formation
• Scientific discovery and responsible extraction
• Ethical sourcing with complete transparency
What was once hidden deep within the Earth is now ready to be shared, carefully, respectfully, and responsibly.
