For sale is a very fine dumortierite in quartz, from Bahia state, Brazil. Dumortierite is a rare aluminum boro-silicate and the world’s most outstanding pieces of the species are found from this one Brazilian location. Five years ago there was a flood of these specimen on to the market, (thou examples the size of this specimen were quite uncommon) today they fetch a considerably higher prices, when available, considering how pretty they are I am not surprised, (check the web). This pristine, single crystal, has very high luster on three faces, the specimen is internally clear and transparent. As I said before single natural (not polished) crystals of this size are hard to obtain. Please remember our prices are in Australian dollars.
