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 work directly with trusted suppliers around the world to ensure responsible mining, fair labor, and environmentally conscious sourcing.
