Johnny Kneller

Johnny Kneller was born in Prague in 1946. He began his career at the Kneller family company in Antwerp and from there, his lifelong fascination with large diamonds was born. In 1981, he struck out on his own with considerable knowledge of the rough diamond business. In 1985, he took over South African Sightholder Krochmal & Cohen, quickly steering it on a remarkable growth path.

For over a quarter of a century, Johnny has cultivated an extraordinary level of expertise in both large and coloured diamonds. This personal passion finds him as an almost permanent guest at the worlds most exclusive diamond auctions.

Not surprisingly, the world's leading dealers seek his advocacy and guidance on a daily basis.

Johnny lives in Antwerp and is responsible for Group Sales and Distribution.
