Frequently asked questions

• What are Dzi agate beads and how are the patterns made?

  Dzi (pronounced "zee") beads are agate — a chalcedony quartz — etched and dyed to produce the symbolic banded patterns associated with traditional Tibetan Dzi. The base bead is natural agate, typically rounded or barrel-cut. The patterns (eyes, stripes, lines) are surface-applied: a resist is painted onto the bead, then the exposed agate is darkened through heat and alkaline soaking, and often dyed to deepen contrast. Modern Dzi-style beads from China and India use this same technique. The result is a durable agate bead with high-contrast graphic patterns — distinct from antique Tibetan Dzi, which are a separate collector category.
• Are these antique Tibetan Dzi or modern Dzi-style beads?

  Bead-trade Dzi, including what Dakota stocks, are modern agate beads produced using the traditional etch-and-dye technique. Antique Tibetan Dzi are collector items that trade in a completely different market at four- and five-figure prices per bead, and are not sold by strand. Modern Dzi-style beads are designed for jewelry construction — they carry the same graphic patterns (two-eye, three-eye, nine-eye, tiger-tooth, etc.) on a sound agate base, calibrated and drilled for stringing. If you need provenance documentation for an antique piece, that's outside the strand market.
• How should I care for Dzi agate to preserve the patterns?

  The agate base is durable at Mohs 6.5–7, so the bead itself resists scratching in most jewelry applications. The pattern, however, sits at and just below the surface and depends on dye stability. Clean with mild soap and a soft cloth, then dry thoroughly. Avoid ultrasonic and steam cleaners, prolonged soaking, bleach, acetone, and other solvents — these can lift or fade the etched designs over time. Store away from prolonged direct sunlight to slow any color shift. With reasonable care, Dzi agate holds up well in bracelets, necklaces, and earrings.
• What projects work best with Dzi agate beads?

  Dzi agate is most often used as focal or accent beads in malas, men's bracelets, layered necklaces, and culturally-themed designs where the graphic pattern is the visual anchor. Barrel cuts (Dakota stocks these heavily) are the traditional Dzi shape and read as statement beads; rounds work as spacers or full strands when you want pattern repetition. Pair with matte black onyx, sandalwood, rudraksha, brass or copper findings, and other agate or jasper tones. 8mm and 6mm dominate Dakota's stock and string well for wrist-worn pieces; 10mm and 12mm suit larger malas and men's designs.
• How is Dzi agate different from plain black agate or onyx?

  Plain black agate and onyx are solid-colored chalcedony, often dyed uniformly black with no surface pattern. Dzi agate uses the same chalcedony base but adds the etched symbolic designs — eyes, stripes, lines — that define the category. In the bead trade, "Dzi" specifically refers to the patterning technique, not a different mineral. If a strand is described as Dzi but shows no etched pattern, it's likely been mislabeled. Treatment details (dyed, etched, heated) should appear on the individual listing — ask before buying if a specific SKU doesn't list them.
