Ortak Jewellery Design Process

Ortak designers use modern technology and our dedicated research of history and fashion to create gold and silver Jewellery collections. This benefits our customers who can be assured that Ortak Jewellery is always at the contemporary leading edge and authentic to its design roots.

Model Making

This process is carried out by Ortak's craftsmen using techniques and methods handed down over decades. The final master is the result of close cooperation between designer and craftsman - giving the piece a real handcrafted pedigree. The designer's concept and drawings are used by the model maker to create the original piece of Jewellery - known as the 'Master'.


When the masterpiece of Jewellery is complete, it is used to make a high-tech mould, which in turn is used to make wax replicas of the Jewellery.


The wax replicas are placed in steel flasks which are then filled with investment powder. The flasks are then heated in a furnace to 550°C which solidifies the powder and evaporates the wax leaving behind a perfect impression. Molten gold or silver is then poured into the flasks, allowed to cool, then dismantled to reveal the Jewellery in casting form.


These castings which are perfect replicas of the original masters are then hand finished to Ortak's high standards - adding fittings and settings before being dispatched to all corners of the world.


For the manufacture of jewellery and silverware, precious metals are not used in their purest forms. Instead, they are alloyed with other metals. It is not possible to discern by sight or by touch what the precious metal content of an alloy is.

Our customers can rest assured that all of our products come with a guarantee of the precious metal content through the 700-year-old practice of third-party independent hallmarking.

The 1973 Hallmarking Act makes it unlawful to describe an item over a certain weight as gold, silver or platinum without an independently applied Hallmark.

  • All Silver articles weighing more than 7.78 grams must be hallmarked.
  • All Gold articles weighing more than 1 gram must be hallmarked.
  • All Platinum articles weighing more than 0.5 grams must be hallmarked.
  • All Palladium articles weighing more than 1 gram must be hallmarked.
