Frequently asked questions
-
Where does crazy lace agate come from?
Crazy lace agate is sourced almost exclusively from Chihuahua state in northern Mexico. The deposits there produce the distinctive swirling, looping, lacework banding that gives the stone its trade name. Some dealers also market the material as "Mexican Lace Agate" or "Laguna Lace Agate"; all three names refer to the same Chihuahua-sourced banded chalcedony. -
Is crazy lace agate dyed?
Often, yes. Across our current active catalog of 55 strands, 37 are dyed and 11 are tagged natural — a roughly 77/23 split toward dyed. This reflects the broader bead trade, where dyed crazy lace is more common than natural because the bright colors are visually striking. We tag treatment at the SKU level and disclose it on every listing so designers can choose either with full information. -
What's the difference between natural and dyed crazy lace agate?
The pattern is the same — both are real Chihuahua crazy lace agate with the signature swirling banding. The difference is color. Natural crazy lace is earth-tone: red, yellow, cream, tan, gray, soft pink, with occasional black inclusions. Dyed crazy lace shows colors that don't occur naturally in the Mexican deposits — electric blue, deep purple, fuchsia or hot pink, and uniform candy-color gray. The palette test is simple: earth tones are natural; bright or jewel tones are dyed. -
How durable is crazy lace agate?
Mohs 6.5–7 — durable enough for any jewelry application, including rings, bracelets, necklaces, and earrings. It is true banded chalcedony, the same mineralogy as the rest of the agate family. Standard care is soft cloth with mild soap; avoid ultrasonics on dyed strands, which can leach the dye over time, and avoid sustained UV exposure on heavily-dyed material. -
What sizes and shapes does Dakota carry in crazy lace agate?
Our current crazy lace catalog spans 4mm, 6mm, 8mm, 10mm, and 12mm in round cuts, with the heaviest stock at 8mm (15 strands). Faceted and rondelle cuts surface in select sizes. The full size and shape grid is filterable on this page — and treatment (natural vs. dyed) filters alongside size so designers can isolate exactly the strand profile they need.
