The EU is set to take the shine off Russia's diamond trade.

Hello and you're listening to the Marketplace Morning Report, live from the BBC World Service on

the Anna Byrne.

Thanks for tuning in.

Russia is the world's largest producer of rough diamonds. and are one of the few major exports still untouched but now the European Union and the G7

are set to impose a ban on them the BBC Sophia Batiza, travelled to Antwerp in Switzerland

where one in four rough diamonds previously came from Russia to find out more.

I'm in Andrup's Diamond District.

It's a very small area, only about one square mile. You wouldn't think that this is the largest diamond

district in the world, but more than 80% of all rough diamonds that are mined across the globe are traded here.

This was the gateway to the world for Russian diamonds.

Before the invasion of Ukraine, one in four diamonds traded here came straight from Russia.

But all that is changing. The EU has just unveiled sanctions banning the input of diamonds mined in Russia.

Here we have some diamonds, which will affect people like Thierry, who's been a diamond

trader for more than 30 years.

Before the war, half of all his stones came from Russia.

It takes a while to shift your business

from one supplier to the other.

It gives you a lot of headaches headaches but it's doable.

Tierri has been able to switch his inputs to a mine in Canada but some of his

colleagues have not been so lucky. Some of the companies were very much reliant on their business with Russia.

It was a very big business. The turnover of some of the companies were big traders in Russian diamonds, they went out of business.
