TXF97CD5: This rare arsenate of sodium, calcium and magnesium displays an intense and uniform yellow color and crystalline appearance, on a rock matrix partially covered by Calcite which gives a beautiful color contrast. Also has small dark grains of Hausmannite.
The Berzeliite comes from the type locality for the species, the Långban metamorphic manganese-iron deposit with its very complex skarns and pegmatites, which has provided a whopping 78 type localities of mineral species.
