Gemstone markets

CHANTABURI IN THAILAND

Many of our gems are bought on this market. Buyer and seller have a kind of negotiator who work on commision and the deals are closed using a kind of auction system. Prices can vary a lot depending on avalibility and demand.

Bild 1 med skylten som visar var området börjar där det är ädelstensmarknad varje helg fredag-söndag i Chantaburi. Det är många säljare och köpare under marknadsdagarna. I axelväskorna finns ofta ädelstenar för mycket stora värden, 1000-tals dollar. Here does the area start where it is gems market friday to sunday. Many buyers and sellers during market days. In the shoulderbags there can be gems of huge values, 1000s of dollars.

Bild 1 visar köpare som väljer bland ett parti safirer. Bild 2 visar köpare som väljer bland ett parti rubiner. Bild 3 visar köpslagning och tydligen inte överens, ...VERY EXPENSIVE... Pic 1 buyer choose from a LOT of sapphires. Pic 2 buyer choose from a LOT of rubys. Pic 3 buyer and seller do not agree, ...VERY EXPENSIVE...
