Bharat Diamond Bourse Vice-President Mehul Shah, who heads the Bharat Diamond Week, said: “We are looking forward towards the launch of 2019 edition of the Bharat Diamond Week, 14 to 16 October. BDW invites buyers across the globe as well as within India. Selected buyers will be allotted complimentary hotel accommodation. Members of Bourses affiliated to WFDB will be always at a priority. This is also an inter-bourse show which proved to be such a successful concept last year. We are building on those first two shows to take it to the next level with higher numbers of exhibitors and many more buyers. As with the 2018 shows, we want to create maximum coverage for our small and medium-size companies.”

Above all the guest of honor to BDW 2019 is the vice president of WFDB and president of Shanghai Diamond Exchange Lin Qiang with the Members of SDE.

BDB President Anoop Mehta said: “The inaugural shows and the high level of demand from visitors and exhibitors alike showed that we had to stage a show in 2019. The exhibitors will again be treated to typical warm and welcoming Indian hospitality as we show them that our diamond companies can supply them with absolutely any diamond they need in any shape, size or color.

“Each Indian company that wins the right to display at the Bharat Diamond Week is entitled for one booth only. Trading of Synthetic or Lab Grown Diamonds are banned in BDB, therefore there is no room for synthetics or lab grown diamonds in BDW.”

Mr Mehta added: “These inter-bourse events have proven their value at other diamond exchanges also, and it is only right that India, as the world’s primary cutting and polishing centre, should hold a fair to showcase the diamonds that we have available for sale. The Bharat Diamond Week puts buyers directly in touch with suppliers in a convenient setting, saving time and expenses as the exhibitors and their goods can be easily and quickly found, thus making the fair an efficient visit. We will be announcing further details in coming weeks.”

The biggest attraction for the show is that being a pre Diwali time, it’s the perfect opportunity for best buying deals.
