Roweite is a rare calcium-manganese borate with hydroxyl; not known previously in large and dramatic crystals before a surprising Chinese find of around 2017 from the "Huanggang Mines" - which actually quickly turned out to be from this lesser known location also in Northern China. This attractive display-quality specimen features a cluster of robust and tan-colored Roweite crystals in elegant fan-shaped sprays on a matrix of Olshanskyite and Calcite. The crystals measure from 1 to 2.3 cm across (this is quite large!) and there are at least two dozen crystals that compose the various fanned aggregates. The Roweites have a satin luster and are just slightly translucent on the edges. They sit on an off-white to yellowish matrix of granular Olshanskyite on top, with Calcite on the bottom of the piece. Olshanskyite is a calcium borate hydrate. Roweite and Olshanskyite came out in several small pockets in one area of the Shijiangshan Mine in 2017, and the specimens subsequently evaporated into the worldwide collector's market. The Roweite may have even been a single small pocket zone collected all at once. They are the absolute world's best of species compared to any other known locality and the crystals on this piece are exceptional and without any damage. This elegant miniature is one of the better pieces I have seen, and also has rather large crystals with great balance and composition. It was on display at the TGMS 2022 showcase of the Young Mineral Collectors, from the Tom Zhang collection (to us, by exchange).
