Ph. Karl Hahn & Co. was founded in 1905 by the current generation's great grandfather Philip Karl Hahn. During the first years buisness was mainly focused on cutting blue Sapphire's from Australia.
Between 1914-1945 the wars and the great depression had a tremendously negative impact on the gemstone industry.
After 1945 the company bounced back mainly as a supplier of rough gems from Brazil and Africa. A branch of the family had earlier emigrated to Brazil and was running mining operations producing Aquamarine, Amethyst, Rosequarz and other stones. This cooperation with Brazil was very helpful in the aftermath of the war.
