Amsterdam has a long heritage in the diamonds, and has been a major diamond centre since Sephardic Jews introduced the diamond cutting industry in the later 16th century.

Jewish diamond industry in Amsterdam

The different diamond factories in Amsterdam are a reminder of Amsterdam's flourishing Jewish diamond industry before World War II. The diamond trade was dominated by Sephardic Jews from Spain and Portugal with international commercial contacts in the areas where diamonds were to be found. Besides the trade, the cutting of the diamonds also became a predominantly Jewish business.

Jews were not allowed to join guilds, so they were unable to engage in traditional trades. As there was no guild for diamond cutters, Jews were free to specialise in this trade from the 17th century onwards.

In the early 20th century around 30% of the male and 10% of the female Jewish population of Amsterdam worked in the Diamond industry.

After World War II Amsterdam lost its leading position on the world market to cities such as Antwerp, New York, Tel Aviv and Mumbai, but its reputation as a city of diamonds lives on in its factories.
