Devilline is a sulfate mineral with the chemical formula CaCu 4 (SO 4) 2 (OH) 6 ·3H 2 O. The name originates from the French chemist's name, Henri Etienne Sainte-Claire Deville (1818–1881).

2014年1月25日 · Devilline is a rare and unusual secondary mineral found in the oxidized portions of copper sulfide ore deposits. Because Devilline occurs in such oxidation zones, this mineral often is of post-mining origin. Devilline is found in mines all around the world. Color: Blue, Blue green, Blue white, White, Dark green.

Devilline is a sulfate mineral with the chemical formula CaCu4 (SO4)2 (OH)6•3H2O. The name originates from the French chemist's name, Henri Etienne Sainte-Claire Deville (1818–1881). Devilline crystallizes in the monoclinic system.

Green, bluish-green; green in transmitted light. Devilline Group. Named in 1872 by Félix Pisani in honor of Henri Étienne Sainte-Claire Deville [March 11, 1818 Saint Thomas, Virgin Islands - July 1, 1881 Boulogne, Hauts-de-Seine, Ile-de-France, France], French chemist. He was professor of chemistry at the University of Besançon from 1845 - 1851.

2024年10月11日 · Devilline is a copper sulfate mineral that forms in the oxidation zones of copper deposits. Its unique crystal structure and vibrant hue are not just eye-catching but also tell a story of geological processes spanning millions of years.

Exquisitely perched on matrix are rosettes of devilline, an uncommon hydrated calcium-copper sulfate. The specimen is smothered in teal-colored crystals of devilline, to 2 mm across. Beautifully crystallized and colorful, this is also one of the ultimate beautiful rarities that are hard to get in any quality beyond micros!

Devilline (or devillite) is a hydrated sulfate from the oxidation zone of copper deposits. It is also found in neo-formation in slags. It was named in honor of the French chemist Henri Etienne Sainte-Claire Deville, inventor of the first industrial aluminum manufacturing process.

Devilline is one of the classic copper minerals of Europe, and the finest of these are from Spania Dolina (formerly called Herrengrund). This beautiful Devilline specimen has numerous emerald-green "rosettes" of tabular blades, on matrix.
