Hi Lalitha, Are you looking at gold or I gm gold, or imitation jewellery ? If you are looking at 1 gm Narayana pearls and taras is the best. Imitation you can get at Jhillmill and also on the pavements at Pondy Bazaar. Gold ones you can get at GRT or any of the jewellers in chennai will have it.
Sorry for the daely in replying, Tara's is on Kutchery Road two buildings away from the Jain temple, hard to miss.
Hai Guy You can get silver dipped in gold from Sukura jewellery at Mylapore. A lot of varities are available there. Viji
