Larger specimen with layers of orange glowing (SW UV) Walstromite. Benitoite occurs with the Walstromite and Sanbornite and shows a blue glow under SW UV. The Fresnoite is very good and is shown in the third from the last photo as yellow crystal grains to 2mm.
Walstromite is named in honor of Robert E. Walstrom (1937-2022), who discovered it while prospecting for barium. From Mindat: He has 12 minerals new to science to his credit, already published (2008), with more in the works. I never knew Bob real well, but from what I gather he was an amazing field collector as well as a great mineralogist.
