"world affairs section" vs "business section"

[Ilovepsycho]

While many of South America's duty-free shops stock reasonably priced gemstones, Rio de Janeiro's offes a particularly wide selection that includes aquamarines, citrines, tourmalines, amethysts and emeralds. One indication of the city's excellence in ths regard is the presence of Brazil-based H. Stern, a renowned international jewelry firm that operates four stores in the airport.

Also special to Brazil are stones of lesser quality - rose quartz and other rock crystals - which are handcrafted into a fantastic menagerie of exotic birds and animals that can cost up $1,000. Other local goods inspired by the coutry's rich variety of fauna and flora include such decorative handicrafts as wall hangings, tablecloths and tapestries.
