Nature not only gave Brazil a beautiful environment and the world's most abundant fresh water, it also granted Brazil rich mineral resources. And among them, gems are the most desirable: imperial jade, emerald, tourmaline, aquamarine and sapphire.
Brazil's total production of all kinds of precious stones accounts for one third of global output, and 80 percent of mined gemstones are exported overseas. The industry is truly one of the country's jewels.
Whether in Sao Paulo, Manaus or Rio, you can find jewelry stores. In some gem shops, you can see the machining processes: design, cutting, polishing and examination to inlaying the gemstones. Polishing is the most complex work. Once polished by the rapid rotation of the grinding wheel, a stone will lose 60 percent of its original weight.
