Locality: Brilliant, Marion County, Alabama, USA (See on Mindat)
Size: 6 x 2 x 9 cm
Weight: 107 g
Description:
This petrified wood specimen bears a coating of fine, druzy quartz crystals that fluoresce a butter-yellow color under either LW or SW UV. Oddly, I have other specimens of this material that exhibit both fluorescing and non-fluorescing zones of quartz crystals on the same specimen. Shown here is the view under SW UV and in ordinary room light.
Summary of luminescence responses:
Quartz (Mindat) (RRUFF)
- Fluorescence under Longwave (365nm LED) UV light: Yellow
