4. GEM MARKETS - For those dazzled by the mystical East and its jewels, head for the Gems Market in Amphoe Bor Rai. It is famous for stunning collections of gems for sale, especially the the Siamese rubies. These rubies are renowned all over the world for their clarity and deep red colour. Three major markets, Hua Thung, Sa Yai and Nong Bon form this famous Gems bazaar, but there are other smaller gem markets like, Ban Nong Bon, Ban Sai Yai and Ban Ta Ngam around. A lot of unsavoury gem scams riddle Bangkok jewel markets and it is best to research, do your home work before investing in these expensive baubles. For a more extensive gem hunt, visit Chanthaburi. Located 250 kilometers away from Bangkok, it is a small town, a major trading center of gems in SE Asia and an estimated 80% of the world's rubies and sapphires change hands there. Still a cottage industry, Chanthaburi gem market known as Talad Ploy is open on Fridays, Saturdays and Sundays from 11-6 in the evening.
