The Intergem 2015 is at the ready. Preparations for the most important event in the gemstone industry are in full throttle.

In the face of increasing global competition and diminishing supply of rough stones the importance of the industry’s signature fair is unmistakable.

The incomparable international centre of the gemstone industry is located in Idar-Oberstein – with the Intergem as its flagship. “You will probably never find this concentration of know-how in craftsmanship, trade, research and all the other services concerning fine gemstones anywhere else in the world”, says Kai-Uwe Hille the managing director of Intergem.

“The local industry is facing major challenges due to the inclining competition for the last resources. Many rarities can solely be found here in Idar-Oberstein.”

The long grown relationships of the lapidaries to miners and traders in the countries of origin and rough stone treasures accumulated over decades are the basis of the Intergem’s one-of-a-kind variety which is presented once a year at the beginning of October.

Visitors are sure to not only find an unmatched range of unique gems, pearls, gemstone jewellery and a broad range of technical services but to experience know how first hand. Institutions and colleges present their expertise at the newly created ‘Competence Centre’.

The German Gemmological Association will demonstrate their gemmological work focussing on the microscopic possibilities for the determination of origin of rubies, sapphires, and emeralds as well as microscopic characteristics for the distinction of natural and synthetic stones.

Additionally graduates of the field ‘Gemstones and jewellery’ of the Trier University of applied sciences will present various projects – showing how the combination of modern techniques and the collaboration with local companies can lead to astonishing results like the automatic production of 3-D forms made of stone in combination with electroplating.

Furthermore students of the Idar-Oberstein class of gold, silversmiths, and gemstone setters present their creations and will also demonstrate the art of enamelling.

Last but not least the supporting programme will once again be top of the notch: On Friday 02. October the foyer in the halls will turn into a vine tasting lounge presented by the vineyard ‘Korell Johanneshof’ from Bad Kreuznach – and on Saturday evening the Intergem calls to the fair party at the PH1 club at Park Hotel Idar-Oberstein.
