Common carnelian fakes & look-alikes

• Dyed agate / chalcedony. Color is unusually even or follows straight banding lines exactly; backlit, dye can look like it sits along layers rather than glowing through the stone.
• Heat-treated agate. Very vivid, uniform orange-red; heating brown agate produces bright carnelian color that's more saturated than typical natural material.

Simple at-home tests

1. 1Backlight the stone. Natural carnelian shows a cloudy, uneven color distribution when held to light; dyed stones often show even color or dye following banding.
2. 2Scratch test. Real carnelian is quartz (Mohs 7) and scratches glass; plastic imitations won't.
3. 3Loupe the banding. Dye concentrated between chalcedony bands (rather than uniform body color) indicates a dyed agate.

At-home tests are indicative, not definitive — for valuable pieces, get a professional gemologist's opinion.

The bottom line

Cloudy, uneven natural color that glows through the stone points to natural carnelian; perfectly even color or dye following banding lines indicates treated or dyed agate (still real quartz, just enhanced).
