Contributor writes, “Selenium billion from Luciteria, from top to bottom the sample reads: Se34 / Selenium / ONE OUNCE/ 99.9% PURE with the Luciteria Science atom logo below it. The packaging has “Exotic Bullion Series” in italics below the main Luciteria logo, and at the bottom their website, luciteria.com. The packaging also has several mathematical formulas and equations on it, but the contributor does not recognize any of them.”

Tiny, lab grown crystals of an unusual, dark blood red allotrope (form) of Selenium. This sample has the monoclinic crystal structure. Photos of this form are rare. This allotrope is different from the amorphous bright red powder that precipitates from reactions that make elemental Selenium.
