In July 2013, a GIA team visited the China Diamond Exchange Centre in Shanghai during an extensive trip undertaken to document China’s gem and jewellery industry. The trip was arranged by Dr Tao Hsu, technical editor for Gems & Gemology, and the Exchange was an important part of the itinerary.

The China Diamond Exchange Centre is home to the Shanghai Diamond Exchange (also known as the Diamond Exchange). Before it was established in October 2000, taxation—including import tariff, value added tax (VAT), and sales tax on imported diamond—was around 35 to 40 per cent. Diamond taxation policy is now very favourable in China, with VAT at only 4 per cent. (In reality, all goods imported into China are charged 17 per cent VAT, but 13 per cent is refunded for diamonds, leaving the net VAT charge on diamond at 4 per cent.) This lowered taxation came about due to input from the Diamond Exchange, and it was instrumental in greatly reducing the quantity of diamonds smuggled into the country to avoid the higher taxes.

The Exchange’s Influence

The Chinese diamond industry benefited greatly from the formation of the Diamond Exchange. Before it was established, the official annual diamond import value was about US$1 million. By 2011, the import value had reached over US$5 billion, of which $2 billion was imported solely into mainland China. While imports dropped by 10 per cent in 2012 due to worldwide economic conditions, indications for 2013 are that the import figure will be higher.

The Diamond Exchange joined the World Federation of Diamond Bourses in 2004, and hosted the 33rd World Diamond Conference in Shanghai in 2008.

The Mission of the Exchange

The Diamond Exchange is China's only legal location for diamond import and export. Set up by the central government, its mission is to make trade more convenient by simplifying diamond import and export procedures.

According to Chinese law, all imported diamonds must go through the Exchange and several procedures must be followed. One of those is that diamonds imported into China must be declared and sealed in customs, or they are considered illegally smuggled. The diamonds are unsealed, inspected and assessed by an expert at the Exchange before taxation is imposed.

Kimberley Process Certificates

Kimberley Process certificates must accompany rough diamonds. Their mandatory inspection is strictly carried out in China. A special department in the Diamond Exchange has been set up for inspecting and registering Kimberley Process certificates. Once the certificates pass inspection, the rough can be sold in the domestic market. China was elected as the Deputy Chairman Country of the Kimberley Process in 2013. In 2014 China became the Chairman Country and one officer of the National Bureau of Quality Inspection will take the position of Chairman.

Open Platform

The China Diamond Exchange Centre is a totally open platform that welcomes diamond dealers from all over the world. It has more than 350 members, of which 67 per cent are overseas members from Israel, Belgium, Great Britain, France, the United States, Japan, Africa and other countries. There are 114 member diamond companies from mainland China, 62 from Hong Kong, 50 from India, 32 from Israel, 23 from Belgium, and the rest from other countries.

Membership Requirements

A diamond company that wants to be a member of the China Diamond Exchange has to meet certain requirements. The first requirement is that the company must have been engaged in the industry for at least three years and must be familiar with its operation. Secondly, the company must be introduced by two registered members of the China Diamond Exchange. A new member has to go through a one-year probationary period.

The third is a financial requirement: a mandatory US$20,000 (£12,000) one-time admission fee. The fee is refundable if a member wants to withdraw from the Exchange as a result of unsuccessful business endeavours or for several other reasons.

Another important condition is that a diamond company operating in China must be approved by the Diamond Administration of China (DAC) and registered according to Chinese law. After approval and licencing by the DAC, a company is allowed to engage in import and export business and take part in customs, tax administration and Kimberley Process procedures.

Main Functions of the DAC

The DAC and other government organisations jointly control day-to-day diamond imports and exports across the country as well as trade within the China Diamond Exchange.

The main functions of the DAC are administration and statistical analysis of national diamond imports and exports under normal trade conditions; examination and verification of transactions under the rules of the Diamond Exchange, as well as supervision of the Exchange’s operations; and coordination with other government officials inside the Exchange regarding issues relating to the diamond trade. The DAC also conducts the examination and approval of the establishment of foreign-invested diamond companies, and daily regulation of their operations. It participates in the formulation of regulations and policies concerning diamond import and export and other diamond transactions, and provides services to the Exchange and to domestic and foreign diamond companies.

Building and Departments

The tower that houses the China Diamond Exchange Centre is an impressive structure in Shanghai that covers an area of 49,000 square metres. The building is designed to be a one-stop shop for the diamond trade and boasts the latest in security, communications and technology. The DAC is located in the tower, along with other diamond-related government organisations.

China Diamond Industry Development

Diamond jewellery entered the mainstream Chinese market in the 1980s. Along with rapid economic and social development, the continual improvement of people’s living standards, and the fast rise of consumerism, diamond jewellery sales have been increasing at a rate of 15 to 20 per cent a year. China is now the world’s second largest consumer market for diamonds, overtaking Japan.

China’s diamond-polishing industry also started to grow significantly in the early 1980s, and this growth became more rapid in the 1990s. Currently, China is the second largest diamond-polishing country, after India. China polishes over six million carats of diamonds annually and employs over 50,000 polishers in more than 80 medium and large factories. Most of the factories are located in Guangdong, Shandong and Shanghai. China has developed a niche for high-quality precision cutting and markets this product as China Cut.

Most of the diamond polishing in China is subcontracted work for foreign clients, who hire domestic firms to polish their diamonds. There are also numerous jewellery manufacturing firms producing diamond jewellery for export.

All of this phenomenal growth is due in part to the policies and organisation of the China Diamond Exchange Centre in Shanghai.
