THE blockbuster Titanic has created more than just film history. When the heroine Rose DeWitt Bukater played by Kate Winslet wore a brilliant sapphire pendant, a symbol of her passionate love affair, no film director could have ever foreseen the impact it would have. Back home in Jaipur, the famed gem traders are reaping an azure fortune as a blue fire rages through Johari bazaar. Blue was the colour of Roses love. Blue is the colour of Jaipurs trade today. The success of the film fuelled a fad in the US for the blue stone. Except, sapphire was too expensive as an accessory. So India discovered the cornflower blue tanzanite and a recession- hit Jaipur flooded US markets with it a year- and- a- half ago. Today it controls about 80 per cent of the global trade in tanzanite. The highest price commanded by a single carat of tanzanite Rs 22,000. The Titanic may have sunk, Roses trillion sapphire may be resting on the ocean bed but tanzanite has helped the Jaipur gem trade stay afloat... perhaps soar would be a better way to describe it.
