Billions dollar worth of jewelries exported to Switzerland
Billions dollar worth of high-grade jewelries have been exported in the last two years from Vietnam to Switzerland , where the jewelries are smelted to get gold.
Auctioneers Sotheby's said on Monday that a rare pink diamond valued at up to $A39.11 million would go on sale in Geneva in November, dubbing it one of the ``world's most desirable stones''.
