The jewelry label Enzo is exhibiting two kinds of precious gemstones - London Blue Topaz and Rosenite - at its Shanghai boutique stores.

Blue Topaz is one of the world's most expensive gemstones. Most come from Brazil. There are several varieties - London Blue, Swiss Blue and Sky Blue. London Blue is the best quality. It's difficult to find these stones on the mainland.

Rosenite has clear rosy color and comes from only one mine in the world, in Tocantins, Brazil.

Consumers can find a new collection of necklaces and rings made of London Blue Topaz and Rosenite during the exhibition.

10 am-10 pm, until Sept 30. Shanghai Capital Malls Hongkou Plaza, 388 Xijiangwan Road, Hongkou district, Shanghai. 021-5633-5630.
