Moroccan Seam Agate

Frequently asked questions

• What gives Moroccan seam agate its pattern?

  The stone forms as a banded chalcedony in cavities within Moroccan volcanic and sedimentary host rock, where silica-rich solutions deposited rhythmic layers around inclusion points. The diagnostic patterns are concentric "eye" rings centered on darker focal spots and tight seam-line inclusions that thread parallel or wavy through the stone. Both features are intrinsic — they are part of how the rough crystallized.
• Where does Moroccan seam agate come from?

  Multiple deposits across Morocco. The trade name "seam agate" emphasizes the linear seam-line inclusions; the same general material also circulates as "Moroccan agate" and "Moroccan eye agate" depending on which pattern feature the dealer is leading with. Morocco has been a working source for banded agate for decades; the material is not supply-constrained globally.
• Is Moroccan seam agate natural?

  Yes. The eye and seam patterns are intrinsic to the rough and survive cutting and polishing unchanged. No reputable supplier dyes this material — the entire commercial appeal is the natural pattern, and dyeing would obscure it. Dakota stocks this material untreated.
• How does Moroccan seam agate differ from other agates?

  The pattern signature is the differentiator. Botswana agate shows fine parallel banding in pink-gray-cream; crazy lace shows swirling looped bands; moss and tree agate show branching inclusions; Moroccan seam shows concentric eye patterns and linear seam inclusions. All share agate's underlying chalcedony chemistry (Mohs 6.5–7, microcrystalline quartz) — the buying decision is the visual pattern register, and Moroccan seam is the eye-and-seam specialist.
• What sizes and cuts does Dakota carry?

  Current Dakota stock skews to focal sizes — large round beads (Dakota's 30mm tag is the indicator) and freeform shapes that show the eye and seam patterns at scale. This material is most striking at larger bead sizes, which is why it's typically used as a single statement element rather than as a uniform strand component.
