This interesting sample of kyanite is accompanied by a small label indicating that it is from Santa Marta, in Lugo. The only town like "Santa Marta" would be Santa Marta de Fixós, but we cannot confirm that it comes from that area. Similar pieces have been collected in Muras, also in Lugo.
The Rubián Magnesite mines are a classic of Galician mineralogy. Currently these mines are active exploiting one of the largest deposits of magnesite in Spain. This specimen, which dates from the late 1970s, shows us a rich aggregate of lenticular crystals of this magnesium carbonate, brilliant, translucent, and with a very aesthetic orange color. It belongs from the Joan Astor collection, with his handwritten and another typed labels.
