FAQ

Are all Dakota Stones gemstone beads genuine?

Yes, all of our gemstone beads are made from authentic, natural materials. Any treatments (such as stabilization or dyeing) are clearly noted.

Are gemstone beads durable for everyday jewelry?

Most stones are durable, but hardness varies. Softer stones (below 6 on the Mohs scale) are best for necklaces or earrings rather than rings or bracelets.

How are Dakota Stones ethically sourced?

We are an ethical business that focuses on responsibly sourced rather than making absolute claims. There is no universal or enforceable certification system for ethically sourced gemstone rough used in beads.

Our sourcing decisions are guided by:

  • Long-standing relationships with trusted partners
  • Clear expectations for labor and working conditions
  • Ongoing evaluation of suppliers and materials
  • Transparency about what is—and isn’t—documented in the industry
Where are your gemstones manufactured?

Most of our gemstone beads are manufactured in China and India, with select turquoise products sourced and produced in the United States.

Our primary manufacturing partner in China is a long-standing, multigenerational relationship that dates back to 2003. In India, we work primarily with smaller, family-based operations and purchase ready stock rather than commissioning production.

Do you work directly with miners?

When possible, yes. In many cases, however, direct sourcing from miners is not feasible due to cost, logistics, or material availability—especially for lower-value stones like jaspers and agates.

Instead, we often work with trusted intermediaries who have established relationships within the mining and cutting communities. This is common and unavoidable in the natural stone industry.

Why don’t you list mine-by-mine origins for every stone?

That level of documentation often does not exist—or cannot be verified reliably—for gemstone beads.

Natural stones frequently pass through multiple hands between mining, cutting, and stringing. Rather than offering incomplete or misleading origin claims, we choose to be honest about what we know and transparent about industry limitations.

Have labor conditions improved in your supply chain over time?

Yes. Over the past two decades, labor standards, worker protections, and compensation—particularly in China—have improved significantly as policies shifted toward building a middle class and formalizing manufacturing standards.

These changes have increased costs, but they also reflect progress in worker welfare. We view that as a positive development and adjust our sourcing accordingly.
