The agate cutter Johannes Becker starts a family tradition, until today, in the gemstone and jewellery business.

The gem-mines of Idar-Oberstein are exploited, due to that, the brothers of the grandfather are moving to Brazil from where they supply their relatives with rough stones. Until today, strong family ties are maintained with Brazil.

The Bohemian garnet cutter Gustav Postler is the first to teach lapidaries in Idar-Oberstein to cut on horizontal labs. Amongst the first class of students is the grand grandfather of today's company owners Frank and Stefan Mayer.

The grandfather of today´s owners gets his license as master- cutter and lapidary. He is amongst the first protagonists of today´s popular buff-top cut.

He works for the Green Vaults of Dresden and the Vatican.

After the end of WWII, the diamond and gemstone-cutter Heinz Mayer starts up his own company. His most reputable customer, Harry Winston from New York, is one of the largest diamond-cutters and most respected jewellers in the US.

Political and social factors after the war lead to the disappearance of the diamond-cutting industry in Idar-Oberstein. 
Therefore, Heinz Mayer concentrates more and more on the production of jewellery with diamonds and coloured stones.

In the mid 60´s Heinz Mayer opens its first buying office in Antwerp and the company is expanding rapidly. The strong concentration on rings earn him the nickname "the Ring Expert".

Heinz Mayer is in contact with Wolfgang Joop. Through the co-operation, Heinz Mayer and Wolfgang Joop, a German fashion designer, establish the first fashion brand name jewellery line in the European market.

The Heinz Mayer company celebrates it´s 50th anniversary. Stefan Mayer is invited by the Gemmological Institute of America as a panelist to the GEM-Fest in Basel.

The Heinz Mayer company joins the DeBeers-campaign "Supplier Of Choice".

To schedule the centenary of Rolls-Royce Motor-Cars, Heinz Mayer crafts a bespoke bracelet for this leading name in the world of luxury. It is the only, ever officially authorized piece of jewellery in the 100 years of history of Rolls-Royce Motor Cars.

Presentations take place in Goodwood, Tokyo, Long Island and in the Royal Palaces of Kuwait, in connection with the limited Centenary Phantom.

Another jeweller to a King of the European royalty has been added to the prestigious list of customers of Heinz Mayer OHG.

Stefan Mayer was invited by the Gemmological Institute of America to participate addicts San Diego’s symposium giving a speech on „ Gemstone Treatments: Friend or Foe?“.
It is a great honour for us and symbolises the appreciation of our company through one of the leading institutes in the world of gems and jewellery. This symposium taking place every 7-10 year was opened by no other keynote speaker but the honorary Ms. Madeleine Albright the former minister of state of the United States of America.

Another milestone in the development of the company is the invitation of the German ambassador in Japan to present the Heinz Mayer OHG in his resident in Tokyo. The Japanese premium department store Takashimaya and Rolls-Royce Motor Cars invited the Japanese clientele to treasure the creations of our design-department.
