As British business owners try to come to terms with the vote to leave the European Union, there are fears of the implications a "Brexit" will have.

London perfume maker, Sarah McCartney, said her businesses future "is not smelling so sweet at the moment".

She said she relies on trade with Europe and not only has the cost of raw materials increased, so too will the amount of paper work.

International trade lawyer, Miriam Gonzalez, said trying to minimise businesses uncertainty should be the governments top priority.

She said businesses need to know what the framework for Britain's negotiations with the EU will be, so they can try and minimise uncertainty.

City of London Corporation Policy Chairman, Mark Boleat, said that those uncertainties mean that "some investment is certainly going to be deterred."

While Edwin Morgan from Institute of Directors said the unknowns mean two thirds of its members think a "Brexit" will be negative for their business and cutting investment, redundancies and relocating are all on the table.

10. SOUNDBITE (English) Sarah McCartney, 4160 Tuesdays perfume maker:

"Our market is worldwide and I really, really need to trade with Europe. I buy raw materials from Europe and suddenly they're going to be, well at least, eight per cent more expensive and probably there's going to be ten times as much paperwork."

17. SOUNDBITE (English) Miriam Gonzalez, International Trade Lawyer:

"This country, the businesses in this country need to know what is the framework that the government is aspiring to negotiate, and therefore, whether that is the single market, remaining in the single market or not makes a crucial difference. Trying to minimise the legal uncertainty, I would have thought that is the top priority."

"I think the authorities have handled the market turmoil as well as they could have done. That was done carefully on Friday and no doubt is continuing today but that's a short term issue. It's some of these longer issues that need resolving. It remains to be seen what impact this will have on the growth of the British economy over the next few months, what impact on tax revenue, what impact on foreign direct investment."

21. SOUNDBITE (English) Mark Boleat, City of London Corporation Policy Chairman:

"The fundamentals remain unchanged, Britain is still a very attractive place for business and for investment, but given those sort of uncertainties some investment certainly going to be deterred. Very much depends what the sector is, how important membership of the single market is. But we are going to see some uncertainty and that's going to have an affect on investment."

27. SOUNDBITE (English) Edwin Morgan, Head of Media Relations, Institute of Directors:

"We asked our members immediately after the referendum result came in, what they thought, how they thought it would affect their businesses. Two thirds said that it was negative for them against only about a quarter who thought it was positive. On the specific questions we asked, we asked about investment and hiring decisions and there was also some quite worrying figures. About 36 percent of our members think that they will have to cut investment as a result and about 5 percent of our members say they might have to make redundancies which is obviously quite worrying. There are also some other figures in there on whether or not they'll keep all their operations in the UK or whether they may be forced to move overseas. About 1 in 5 are considering, as we speak, moving some of their operations out of the UK, whether that's to the EU or to somewhere outside it. I mean ultimately we think that our members are very resilient, we think British business is tough and will get through it and will adapt, but certainly at the moment there is a lot of nervousness out there in the business community."

US Secretary of State John Kerry addressed the Oxford Union on Wednesday, speaking on a diverse range of issues, including corruption, Brexit and the problems that face Syria.

Kerry, who planned to attend UK Prime Minister David Cameron's anti-corruption conference on Thursday, appeared to give the prime minister some political cover by describing Nigeria's corruption as a problem its current leaders were working faithfully to address.

Fielding a question on Brexit, he reiterated US President Obama's stance that the US would be looking to make a trade agreement with 27 countries, not one.

Kerry also said that if Russia and Iran don't push Syrian President Bashar Assad to embrace their vision for Syria's future, the there ceasefire would completely fall apart.

"We have to stop and ask on an international basis how it is that a bunch of generals in a country like Nigeria, which had happened previously, and the new president (Buhari) has run against all this, and we are working with him now to change it, but Nigeria saw tens of billions of dollars taken out of the country. Those were schools, those were health care, those were infrastructure, new jobs, hidden in bank accounts around the world."

5. SOUNDBITE (English) John Kerry, US Secretary of State:

"We believe the presence of Britain in EU magnifies its voice, strengthens its ability to be able to impact on global effects, and if indeed the decision were made and your voters make that decision, of course we respect it. But the reality is that in a trade agreement, we're going to be looking to 27 countries, not one. We're going to try and maximize the market place and get the rules in as many countries as we can, because that's the way it's effective, so certainly it will have impacts like that."

7. SOUNDBITE (English) John Kerry, US Secretary of State:

"A political negotiation, a transitional governance body that would run Syria while the constitution is being written and implemented, and then a cease-fire, nation-wide and then and election in a year and a half. Now we are now already five months in so it would be a year and whatever. But that's the envisioned outcome of Iran and Russia. It's pretty similar to ours. The issue is are they going to really push (Syrian President) Assad to embrace it. If he doesn't, the ceasefire will completely fall apart, they will go back to war baring some other kind of intervention that I don't necessarily see on the horizon right now."

LEAD IN:

Diamond encrusted guitars, giant rubies and golden pyramids were just some of the highlights of 2016's run of jewellery fairs across the globe.

But war, political uncertainty and economic turmoil took centre stage this year as most countries reported a downturn in jewellery markets.

STORY-LINE:

In January, Tokyo kicked off a year of glittering jewellery fairs in a sparkling mood.

The increasing economic uncertainty around the globe that marked the end of 2015 did not seem to be weighing heavily on the industry with organisers remaining optimistic about the market as a whole.

The centrepiece of the show was this 400 karat diamond guitar worth a cool US$2 million.

In March 2015 it was certified by the Guinness World Records as the world's most 'valuable guitar'.

It took 68 designers and craftsmen 2 months to complete this unique piece, which is made with 10,000 diamonds.

Other extravagant and novel designs included unique LED jewellery by Tohkoo.Co. Ltd.

The company developed very small LED lights and incorporated then into jewellery items such as earrings and even nails.

By February in Bangkok prospects for the industry were not looking quite so shiny.

The Thailand Gems and Jewellery Fair takes place twice a year and is Asia's second largest trade show, attracting around 1,800 exhibitors.

But traders at the fair reported that the industry was struggling.

Foreign exhibitors were allowed to sell gems and jewellery duty-free. Many local exhibitors cut their prices too. This meant buyers saved about 20 percent, which traders hoped would encourage people to buy more.

The tactics became necessary due to the continuing effects of the global economy knocking onto the gems and jewellery market.

Anthony Peter Brooke, Vice President of the Thai Gem and Jewellery Traders Association said the collapse of China's market had been particularly damaging.

"The China market has now unfortunately collapsed, and that's not the wrong word to use, it genuinely has collapsed. It's probably going to take another 4 to 5 years to get back to the state that it was before. What that means is that prices have basically collapsed. The raw material producing countries are no longer able to sell the amounts that they were before because of this big price differential."

But rubies and sapphires were still deemed safe bets - remaining in demand by the China market and maintaining their price.

Over in Hong Kong, platinum was the saviour at March's International Jewellery Show.

Traders said they were revelling in record low costs for the metal, with prices at their lowest for 7 years.

Platinum remains a popular material for jewellery, particularly in western wedding rings and minimal design pieces.

More than 2,500 exhibitors from 41 countries and regions including India, Thailand and Turkey showcased their products at the 2016 show.

As one of the biggest jewellery consuming countries, gold-loving India said its jewellery industry had been slowing down and Indian traders voiced concern that their government's plan to reintroduce excise tax could result in a drop in sales.

For Istanbul's spring show, luxury and extravagance took centre stage with designers showcasing high-end pieces to customers.

This was the most expensive creation costing 6.3 million US dollars.

The miniature model of the Pyramids of Giza is made of 1,568 pieces of 24 carat gold, and weighs 157 kg.

In the jewellery pavilions, this queen of the Istanbul exhibition gold ring made of 20 and 7 carat diamonds was priced at 345,000 US dollars.

This dagger made of gold and giant rubies was valued at 250,000 US dollars.

And anybody who took a shine to this gold coated Mercedes car would have needed a cool 220,000 US dollars to drive it away.

But behind the luxury and extravagance, Turkish jewellery exporters reported that regional tensions between Turkey and Russia were having an impact on the market.

Relations between Russia and Turkey have soured over the conflict in neighbouring Syria, and have become particularly strained since Turkey shot down a Russian warplane in Syria on November 24.

The Kremlin, meanwhile, was displaying an array of jewellery of its own.

Known for its dazzling golden domes, at the end of March it presented a sparkling collection of jewellery in its museum.

The diamond flowers and gold birds form part of a collection of work on display by award-winning Russian jewellery designer Ilgiz Fazulzyanov.

Fazulzyanov is the first living designer to have been given a solo exhibition in the Kremlin since Pierre-Karl Faberge in 1917.

In Mumbai in August, the annual India International Jewellery Show saw jewellery makers reporting a slowdown in the industry due to soaring gold prices.

But they said designers were compensating by getting more innovative with their designs.

The gems and jewellery sector contributes about six percent to India's gross domestic product (GDP), according to the India Brand and Equity Foundation.

That's due to high local demand and India's role as major centre for cutting and polishing diamonds.

Jewels play an important role in weddings, festivals, or any special occasion in India, making them a much sought after commodity.

Not only jewellery, but also art works, ornaments and even clothing are crafted from gold, silver and platinum and studded with diamonds and precious gems.

One of the highlights of the show was the "Peacock Ring", which holds the Guinness World Record for the most diamonds set in a single ring: 3,827 diamonds in all.

Weighing slightly more than 50 grams, the ring was created by Savio Jewellery and has an estimated value of 2,744,525, US dollars.

The majority of the show had jewellery designed for women, priced from a few hundred dollars to several thousand.

Jewellery designer and blogger, Prernaa Makhariaa says Indian designers were experimenting with innovation, blending traditional Indian styles with Western designs to attract buyers.

"There has been an infusion of diamonds with gold, or diamond with different kind of textures. It's not only diamonds, but even coloured stones are being mixed with gold or with silver or with brass and copper. So India is getting innovative with a lot of different manufacturing techniques and they are trying to play with textures and different kind of materials."

In London, UK traders were confident their products had not lost their sparkle despite the Brexit vote.

Experts at the International Jewellery London show said a weak pound, innovative design and a diverse marketplace for suppliers were just some of the reasons the UK jewellery market was thriving.

Michael Rawlinson is chief executive of The National Association of Jewellers, the main industry body in the UK.

He said: "The British market actually has responded quite well post Brexit at the moment, people have some level of certainty, even if it is leaving the European Union, so we've seen a strengthening of trade in the last couple of months."

With innovative designers continuing to emerge from the UK's most important jewellery schools in London and Birmingham, Rawlinson said 'brand Britain' was as strong as ever.

Examples of innovation came in the form of London-based designer Joanna Boyen of Biiju and her explosion designs and Katy Tromans' fairytale inspired silver rings.

Finishing off the season in October it was back to Istanbul.

Dazzling Turkey's 2nd jewellery fair of the year was this miniature of Istanbul's Camlica Mosque made of gold.

The 300 kilogram piece honouring the largest mosque in Asia Minor (Anatolia) was valued at 10 million US dollars.

But Turkish traders were not celebrating.

Turkey is one of the top three global producers together with Italy and India, but the usually buoyant jewellery sector was waning.

The situation in Syria, terror attacks, a failed coup and a long-running internal conflict with the Kurdish minority all impacted.

Exhibitors attending the show reported an export market drop of 18% overall in the last year according to the Turkish Jewellery Exporters Association. Total exports were 1.4 billion US dollars

Russia, Iran, UAE and Iraq, traditionally the biggest customers of Turkish jewellery, bought fewer Turkish products.

Russia was in 2014 one of the main buyers of Turkish jewellery and gold, but bilateral trade was halted a year ago when Turkey shot down a Russian warplane in Syria.

After resuming business this year, Russia is now the 18th buyer of Turkish jewellery.

Iran is now the top buyer, but the purchase of jewellery and gold has decreased by 38 per cent to 384 million US dollars from January to September compared to the same period last year, according to figures from the Turkish Jewellery Exporters Association.
