The Australian Opal and Diamond Collection has also manufactured and designed for different Monarchs around the globe, such as HRH Princess Mary of Denmark and HM Queen Sylvia of Sweden.

This spectacular piece consisted of a Solid Crystal Opal from Mintabie, South Australia, and surrounded in diamonds. This one piece of jewellery converts into three different pieces; pendant, ring and brooch.
