Cuts & Shapes

EM x4 94

Emeralds are what we do. We specialise in and focus on one of the world’s most beautiful stones. We have many years of experience in cutting rough stones and cover the full range of emeralds from small to large and commercial to exceptional. We purchase all our emeralds via our own office in the Emerald Trade Center in Bogotá. We monitor every stage of processing, starting at the mine, including cutting and polishing, and going on up to our own treatment. We are a direct source for everyone from manufacturers to jewellers. Feel free to browse our pictures of faceted stones, pairs, cabochons and sets.  

Welcome to Lothar Haag Company, worldwide

Mathias-Michael-Haag-300pxIt all started in a small but very famous little town in Germany called Idar-Oberstein. Like no other city in the world, Idar-Oberstein covers the whole range of gemstone manufacturing. Rough stone trading, cutting and polishing, carving, drilling and setting, and jewellery manufacture too.

When my father Lothar Haag founded the company in 1957, he started as a rough stone dealer, supplying the local cutters with all kinds of gemstone from Brazil and Africa. Very soon he decided to open his own cutting shop and specialise in emeralds, which had always been his favourite stone.

Today, the company, in its second generation, is run by my brother Matthias and myself, Michael Haag.

We are both skilled gemstone cutters and worked in the cutting shop for many years. But times have changed and today we always seem to be busy rushing from one part of the world to another. In 2009 the company expanded to Los Angeles, where we opened our first branch office. The second branch office, in Hong Kong, opened not long ago. The third, in Beijing, is our latest project and we are very excited about it. Last but not least, we should mention our purchasing office in Bogotá, Colombia, where we obtain most of our emeralds.

Colombian emeralds are located in an area known as the ‘Emerald Belt’ of the Cordillera Oriental in the Gobernación de Boyacá and Cundinamarca district.

Coscuez Mine

The deposits were exploited by the natives long before the arrival of Europeans in the 16th century and have been worked more or less continuously since then.

Chivor Mine

Chivor Mine

Chivor, formerly Somondoco, the oldest mine in Colombia, north-east of Bogotá. These emerald crystals are longer and cleaner than other Colombian emeralds.
