Agate Gemstone Beads

Frequently asked questions

• What's the difference between agate and jasper?

  Both are microcrystalline quartz (chalcedony). The diagnostic difference is translucence and banding: agate is typically translucent to semi-translucent with rhythmic crystalline bands, formed in cavities where silica-rich solutions deposited layer by layer. Jasper is opaque, colored by mineral inclusions (iron, manganese, organic matter), and typically lacks the rhythmic banding. The Mohs hardness (6.5–7), care profile, and underlying chemistry are essentially the same; the visual register is the buying decision.
• Is moss agate real agate?

  Mineralogically, moss agate is dendritic chalcedony — it shares agate's chemistry but lacks the diagnostic banding. The trade has classified moss agate within the agate family for decades because the look, the polish, and the durability are essentially the same as banded agate. The trade name is what designers search; the technical name (dendritic chalcedony) appears on the variety page so designers know both terms.
• Are dzi beads real or ancient?

  Authentic ancient dzi from the Tibetan plateau are essentially museum artifacts — they don't circulate in the commercial bead trade. Every dzi sold by every bead supplier today (Dakota included) is contemporary manufacture: agate or related chalcedony etched and dyed with the symbolic patterns from the original Tibetan tradition. These are beautiful beads with a meaningful aesthetic lineage; they are not 2,000-year-old artifacts. Sites describing modern dzi as "authentic" without clarifying provenance are conflating bead style with antiquity.
• Is agate dyed?

  Most banded agates (Botswana, crazy lace, Lake Superior, Montana, Moroccan seam, terra) are sold natural — the bands are intrinsic. The exceptions in our catalog are dzi (universally dyed and etched) and druzy (frequently dyed). More broadly in the bead market, bright candy-color agates — electric blue, neon purple, magenta, fluorescent green — are dye signals; natural agate's palette is muted. Treatment should be disclosed per strand.
• How can I tell if an agate is dyed?

  Three signals: color saturation (natural agate is muted earth/pastel tones — anything electric or neon is dyed), color uniformity (natural banding is irregular; dye that's too even is a tell), and dye creep at the drill hole (dye sometimes pools or migrates into the drill channel). The most reliable signal is buying from a supplier that discloses treatment per strand.
