Antwerp and Diamonds

Of course it is universally recognised that Antwerp is globally famous for its association with some of the most exquisite diamond collections in the world. With its rich history and trading traditions that are still employed today, Antwerp is a vibrant and lively city. Diamonds and Antwerp have been closely linked for centuries. One of the biggest and most important diamond centres of the world, Antwerp has played an important role in the diamond industry since the 14th Century during the rule of Charles V (1500 – 1550). The city is Europe’s cultural and cosmopolitan capital.

Monroe Yorke Diamonds operate a buying centre in Antwerp, this way we can source the world's best diamonds at the most competitive prices. 

Lying in the heart of Europe, Belgium is bordered by France, Germany and the Netherlands, and close to the United Kingdom. Antwerp is one of the largest of the world’s ports and is a short half-hour journey to Belgium’s capital, Brussels, headquarters of NATO and the European Union. (EU).

A city of impressive architecture, it is renowned for its art and museums; its much-deserved reputation as a paradise for those who love to shop for designer fashion and accessories. Antwerp’s port is a crossroads of global supply chains and reconciles economic, social and ecological interest wherever possible. It is of great public interest with more than 150,000 people working at the port, supporting the museums and the countless events that take place in Antwerp.

Its role as a globally recognised business centre, open to all cultures and free enterprise has placed Antwerp as the world’s leading centre for the diamond trade.

Antwerp Diamond World Centre



As expected from a centre so renowned for craftsmanship, Antwerp has the best diamond craftsmen in the world. The result of being so closely associated with diamonds has meant that Antwerp is in the forefront of modern techniques and expertise, developed by diamond research centres within the city. The most coveted trade-mark for a perfectly polished diamond would of course be ‘Cut in Antwerp’.

Antwerp’s Diamond Square Mile, a secured area which houses the headquarters of more than 800 international diamond companies, is also the site of four diamond bourses; diamond grading laboratories; brokers; consultants; schools; insurance, security and transport companies, and travel agents. All of this is the centre of a lively social hub with many restaurants and hotels.


The unique atmosphere of the area, enticingly named the Diamond Square Mile is centred around the Hoveniersstraat, Vestingstraat, Pelikaanstraat, Schupstraat, and Rijfstraat, an area adjacent to the Central Railway Station. It is a thriving, bustling business community with a mix of nationalities living, working and socialising side-by-side, while respecting each other’s individual community’s cultures and traditions. The diamond trade is of course at the forefront of this, with import and export trading in polished diamonds, as well as diamonds for industry. Every possible shape or form, quality and colour of diamond is traded here. Antwerp is the home of four diamond bourses (organised trading or market places)

  1. Diamantclub van Antwerpen
  2. Beurs voor Diamanthandel
  3. Vrije Diamanthandel, and
  4. Antwerpsche Diamantkring

These ‘marketplaces’ and commercial infrastructure of diamond trading are an essential part of diamond buying and selling and act as the accepted points of contact for buyers from all global diamond markets.

Diamond Bourses

Antwerp Diamond Trade, The Inside of a diamond bourse


There are diamond bourses in every major diamond centre in the world. Antwerp’s four diamond bourses are members of the World Federation of Diamond bourses.

Bourses are where brokers and manufacturers meet to discuss business transactions to trade rough, polished or industrial diamonds. Discussions and evaluations take place with regard to supply and diamond, and offers are made, all carried out around a table.

Clients from overseas may also enter the hallowed bourses, providing he or she is accompanied by a bourse member who will be responsible for the guest during their visit. For a payment he is permitted to observe and assess diamonds.



Rough diamonds

Locating diamonds is carried out by geologists using traditional methods alongside innovative technology. An assessment of economic viability and yield is carried out on the deposit when found. Less than one in two-hundred deposits of kimberlite becomes a major mine. 6,500 kimberlite deposits have been found world-wide to date. Only fifty of those are sustainable diamond mines.

State-of-the art techniques are used to recover diamonds for the ore, a multi-stage task using alluvial, under-ground, marine and coast methods of diamond mining.
