Our Story

Weltsch A story which began
75 years ago

After the outbreak of World War II, Mr. Oved Ben Ami, Ariel Weltsch's grandfather, travelled to London in 1940, and convinced the principals of De Beers to consent to the initiation of a Diamond Industry in Palestine.

On his way to Belgium, he persuaded a group of Belgian diamond cutters to immigrate to Palestine and help lay the cornerstone for the new diamond industry.

The first shipment of diamonds by the firm I. Henning & co., addressed to O. Ben Ami, arrived in the port of Haifa on April 4, 1940.
