Iolite Gemstone Beads

Iolite is a gem-quality form of the mineral cordierite. It exhibits a fascinating property known as pleochroism, meaning it can show different colors when viewed from different angles. This gemstone primarily displays shades of deep blue and violet, but it can also reveal a clear, light blue or yellow-gray from different perspectives. Iolite's hardness on the Mohs scale is a 7 to 7.5, making it suitable for various types of jewelry.

Facts: Historically, Iolite has been greatly valued by the Vikings, who used it as a polarizing filter to help them navigate during their ocean voyages. This was long before the compass was introduced to the Western world. They referred to it as Viking's Compass. By determining the direction of the sun on overcast days, this gem was crucial in the Vikings' navigation across the seas. Its name is derived from the Greek word 'ios', meaning 'violet', and it has a rich history entwined with exploration and discovery.

Metaphysical / Holistic: Iolite is believed to stimulate vision and insight. It is said to enhance intuition and help one navigate the journey of life more smoothly.

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.
