The name Anhydrite was given by A. G. Werner in 1804, because of the absence of water of crystallization, as contrasted with the presence of water in gypsum.
Fine cluster of dark Stibnite crystals with nice metallic luster from Romania, which has produced the best Stibnites. Very reasonably priced.

Numerous lustrous dark red hexagonal Vanadinite crystals form a dense diagonal path across this specimen.
Vanadinite is mineral belonging to the apatite group of phosphates, with the chemical formula Pb5(VO4)3Cl. It is one of the main industrial ores of the metal vanadium and a minor source of lead. A dense, brittle mineral, it is usually found in the form of red hexagonal crystals. It is an uncommon mineral, formed by the oxidation of lead ore deposits such as galena. First discovered in 1801 in Mexico by the Spanish mineralogist Andrés Manuel del Río in 1801 (From Wikipedia, the free encyclopedia).

Heulandite gets its name in honor of John Henry Heuland, a British mineral collector and dealer.
This specimen is from an exciting new find at a rediscovered old location in Dona Ana County, New Mexico. Though not generally known for great aesthetic quality - these new specimens (I have more) are an exception. This one stands out with it's gleaming bundles of crystals with fine silky luster.
