It appears to be the same rock and the topaz seems to be almost identical. The light patch on the hill is one of the digs. There is also tin found here. Tin mines are found a few miles from here and the children find nodules of tin ore in the streams around the area. It looks like slightly pinkish round lumps of inordinate weight for its size.
Children casually collect stones from streambeds and flats.
This old town was a center of mining for almost two hundred years. The Spaniards extracted gold, silver, lead, iron pyrite and fluorite. The fluorite from the local mountains is beautiful. It comes in pale shades of blue, pink, champagne, green, reddish pink, peach and clear. It appears to be as pale ice chunks when lying damp in the bottom of a bucket.
