Berr & Partners SA



Berr & Partners SA is a company trading in precious stones which was founded in 1986 by two gemmologists, Elke and Thomas Berr. They have been specialising in the international jewellery market since the establishment of their company. The company is based in Geneva, with collaborators in Italy, Spain and France.

Elke and Thomas Berr regularly visit mines in different parts of the world, and have access to the most beautiful natural stones, through a 20 year long collaboration with various partners in countries all around the world. They have the rare privilege of having access to one of the most well known mines in the world, the Mogok mine in Burma, which is the source of gemstones of incomparable quality.

As experts in gemstones, they have been working with the biggest brands in Europe for more than 20 years and they follow the auctions of various auction houses both domestically and internationally.


« We closely follow the market and its fluctuations. Over the past 30 years, we have developed expertise in what is known as “collectors’ stones”. We also offer our clients advisory and support services when they wish to re-sell their treasures. »
