Mancuso Diamonds are manufacturers of the highest quality jewellery. Based in the heart of Sydney's King Street we offer personal customisation of all jewellery, with a specialisation in handmade engagement rings.

The unique ability to sit down directly with our jewellers to discuss ideas that you may have for that very special piece for a loved one, or perhaps yourself.

Unlike most conventional jewellery boutiques, where the same piece is crafted a thousand times over, Mancuso Diamonds specialise in one-off handmade jewellery. 

From a hand drawn sketch to the final product you will be able to deal directly with the manufacturer of your piece, so no more hassle of dealing with the ‘middle-men’. Rest assured that the piece you desire will be crafted perfectly to your specifications and last for generations to come.
