Australian Manufacturing Jewellers

David and Julie Mitcheson are the owners of Seaspray Jewellery, an award winning manufacturing jewellery shop located at Umina Beach, on the Central Coast of NSW, Australia.

Seaspray are Diamond Specialists who source the finest diamonds, handpicked from Antwerp, Belgium, the “Diamond Capital of the World”. 80% of the world’s diamonds are traded here. Typically, only the largest importers in the world can purchase diamonds in Antwerp, Belgium.

Seaspray gains access to this very exclusive market because we are members of Nationwide Jewellers, the largest jewellery buying group in Australasia. The diamonds we select are the best in the world; the ones we don’t select are later sold on the open market to other jewellery stores. The selection is awesome and the price is right.
