Hyderabad is considered the main pearl trading centre in India, because of which the city is also known as the "City of Pearls". The most notable area devoted to the trade is the village called
Chandanpet just outside

Prior to the pearl trade in Hyderabad, pearls were sourced from

, led to the decline of pearl trade in Basra. Henceforth, pearl merchants gravitated towards Hyderabad. Many pearl artisans from Basra have also moved to Hyderabad centuries ago.
Processing
Once the pearls are drilled, they are boiled for about four days to bleach them and rid them of their dark color. They are placed in glass bottles containing
hydrogen peroxide

Pearls are also graded according to color. While pink pearls and black pearls are also considered to be of good quality, white pearls have traditionally been most popular. A good quality white pearl reflects a lovely sky blue color under

Black pearls that have a green sheen and baroque (irregular shaped) pearls that reflect a rainbow of colors are also amongst the more valuable varieties. While black and pink pearls are also rare and beautiful, most traditional Hyderabad jewellery is made with white pearls.
Recently, several pearl makers are exporting processed pearls to markets in Europe and the US. With the capital that they gain from this marketing, they are able to purchase machinery for advanced refinement. In particular, equipment that uses
