16-Inch Gemstones

The 16-inch strand is the industry standard—and no one stocks more of them than Dakota Stones. Browse more than 200 stone types across every color and pattern, from everyday staples like Amethyst and Jasper to collector favorites such as Red Garnet and rare Turquoise mine-runs. Because the strands measure a full 15 – 16 inches, you get enough beads for matching earring pairs, stretch bracelets, or a necklace focal and still have extras for accents.
Need to drill down fast? Use the filter bar to sort by Stone Type when you know the gem you want, or by Color when you’re building a palette first. Shapes range from classic rounds and rondelles to cubes, heishi, chips, and rare designer cuts—each strand calibrated for even sizing and smooth stringing.
Whether you’re a hobbyist replenishing a bead board or a pro assembling a full production run, this category is the workhorse of our catalog: reliable lengths, vast variety, and new additions arriving every month. Dive in, filter your way to the perfect strand, and keep your design queue flowing with Dakota Stones’ biggest collection.

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.
