The article focuses on stibioclaudetite, a new mineral which was recovered at Tsumeb mine in Namibia. It states that the stibioclaudetite, with a chemistry of AsSbO3 is flexible and forms transparent bladed crystals to 6 mm. It is isostructural and has a crystal structure composed of corrugated sheets of AsO3 and SbO3. Results of the electron probe microanalysis, x-ray crystallography, and Raman spectroscopy on stibioclaudetite are also given.

The article offers information on the Milpillas mine in Mexico, one of the famous mineral localities. It is said that azurite crystals and malachite pseudomorphs were gained from the site and have appeared in the mineral market in 2006. It is cited that the mining company deters visits from crystal buyers.

The article discusses the life and mineral collection of Hubert Charles de Monmonier of California. He has established a mineral collection of more than 800 specimens, heavy in native gold and amethyst, and valued at over $7 million. Monmonier's collection was bequeathed to the University of Arizona Mineral Museum in 2007.

The article provides information on red wulfenite from Kuruktag Mountains, Xinjiang Uygur, China. Wulfenite is the only collectible mineral that comes from its localities with a color that ranges from red orange to bright red while some crystals are coated on one or same sides with calcite. It became popular in the market in the early 1990s and its size ranges from microscopic to around 4 centimeter on an edge.

The article discusses the paragenesis of ottensites in China. Ottenites are formed in a well formed stibnite crystal deposits that are partly stripped away and followed by fluorite encrustation. They develop subsequently and sometimes entirely occupied the void forming a spherical combination and is confirmed by X-ray diffraction analysis.
