About Koro

Early in the 1990’s  a group of Ten diverse Western Australian Jewellers formed a Networking Group to work together in promoting their unique Jewellery.
With the assistance of the WA Government under Hendy Cowan, Minister for Commerce and Trade,  Koro successfully participated in several overseas Trade Missions. The Trade Missions showcased the innovative skills and unique creativity of Western Australian jewellers. Koro achieved its objectives by gaining international recognition for the skills, talent and creativity of its people and the Uniqueness of its product and use of  Australia’s precious raw materials.

Today Michael and Werner Dieckmann remain as Directors of Koro, honouring Koro’s original ideas and principals

Located in Perth, WA, they understand that jewellery purchases are often made at extremely important times in one’s life, and more often than not, will remain a memory for a lifetime.

Combining traditional skills with the latest technology, designing original and creative Jewellery superbly crafted and finished in their own Perth workshop.

Michael and Werner have a family history of Craftsmanship and both are Qualified Goldsmiths in the traditional European sense.  Trained in Germany by the old masters and carrying on a tradition of excellence today. Their Craftsmanship is a quality that has been refined and practiced over the course of a career and passed on to the next generation.

Picked up my new ring and love it. Michael was the only jeweller I trusted with my wife's old diamond. Great service and top quality. You pay for what you get but it's the best. Thanks again.
