Israel occupies a paradoxical place in the world's gem trade. The country has no significant indigenous gem-mineral production beyond a few minor occurrences, yet it ranks among the world's leading diamond cutting and trading centres and is among the largest exporters of polished diamonds by value. Israel's gem economy is built almost entirely on imported rough, processed in the cutting workshops of Ramat Gan and Tel Aviv, and exported as polished stones and as finished jewellery, with the Israel Diamond Exchange (IDE) at the centre of the trade.

The diamond industry

The Israeli diamond industry traces its origins to the 1930s, when Jewish diamond cutters fleeing Nazi-occupied Europe relocated to British Mandate Palestine and established cutting workshops in Tel Aviv and Netanya. The industry expanded rapidly in the post-war decades, particularly through the 1960s and 1970s, as Israel became the world's largest centre for the cutting of small and medium diamonds. The Ramat Gan Diamond District, established in the 1960s, concentrates the cutting, trading, polishing, and certification activities into a single high-security urban quarter that today houses thousands of firms and the IDE building complex.

Israeli cutters historically specialised in melée and mid-sized goods, particularly the four-grainer and round-brilliant categories that demanded high precision and consistent symmetry. The country pioneered automated cutting machinery in the 1980s and 1990s and remains a centre for cutting-technology innovation. The Tel Aviv-based Sarine Technologies and Ramat Gan-based DiaMine and Lexus Softmac are leading manufacturers of diamond planning and cutting automation systems used in cutting centres worldwide.

Indigenous gem production

The indigenous gem mineral production of Israel is small and largely confined to ornamental rather than precious stones. The Eilat Stone, a green-blue mixture of malachite, azurite, chrysocolla, and copper-bearing minerals from a small deposit in the Eilat region near the Red Sea, is the country's most distinctive indigenous gem material. The deposit was worked from antiquity (occasionally identified with the biblical Eilat where King Solomon had access to copper and ornamental stones, although the identification is uncertain) and was actively mined for jewellery use through the twentieth century. The deposit is now largely exhausted, and current Eilat-stone jewellery uses material from old reserves or from comparable deposits elsewhere.

Negev Desert occurrences include various agates, jaspers, and ornamental stones used in local lapidary and jewellery, but none on a scale of international significance. Israeli prospecting has occasionally identified peridot, garnet, and other gem minerals in minor quantities, but no commercial deposit has emerged.

Trade infrastructure

The Israel Diamond Exchange in Ramat Gan is one of the world's principal diamond bourses and a member of the World Federation of Diamond Bourses. The IDE building complex contains the bourse trading floors, the offices of the Israel Diamond Manufacturers Association, the Israel Diamond Institute, the Diamond Inspectorate (operating under the Ministry of Economy), the Kimberley Process certification authority for Israeli exports, and dozens of supporting firms. Annual diamond exports from Israel routinely exceed several billion United States dollars, with major markets in the United States, Hong Kong, and the European Union.

For the working trade, Israel is a primary supplier of polished diamonds, particularly in the small and medium categories, and a major source for cutting-technology services. Israeli-cut diamonds are widely recognised for high precision and symmetry, and Ramat Gan remains one of the few cities in the world where one can transact a major diamond deal in person at the bourse and receive Kimberley Process documentation, polished-diamond certification, and export clearance under one roof.
