In April-December 2014, the exports stood at USD 27.16 billion, according to data from Gems and Jewellery Export Promotion Council (GJEPC).
Besides, rejection of consignments is one of the reasons for dip in value of exports.
During the nine-month period of the current fiscal, consignments worth USD 4.81 billion were returned as compared to USD 2.49 billion during the same period last year.
The sector contributes about 14 per cent to the country's total exports.
To check high current account deficit, the government had hiked import duty on gold to 10 per cent.
According to the data, exports of cut and polished diamonds fell to USD 14.78 billion in April-December 2015 from USD 17.32 billion in the same period last year.
Similarly, shipments of gold jewellery contracted to USD 2.87 billion from USD 5.13 billion during April-December 2014.
Exports of gold medallion and coins, however, increased to USD 3.7 billion during the nine month period of this fiscal from USD 1.30 billion in the same period last year.
The government is hopeful that incentives such as 3 per cent interest subsidy and enhanced rate for duty drawback could help contain the decline.
