    • A method of attaching a connection element (130) to a decorative element (110); the method comprising the steps of: providing a decorative element (110) having at least one recess (122); providing a sacrificial body (150) having a first end (151) and a second end (153), the first end (151) comprising a sacrificial cap (152) defining an open chamber (154) configured to receive at least a portion of the decorative element (110) that includes the at least one recess (122); securing the sacrificial cap (152) to the decorative element (110) such that the portion of the decorative element (110) that includes the at least one recess (122) is received in the chamber (154) of the sacrificial cap (152); forming an investment mould (170) over the sacrificial body (150) and the decorative element (110) so as to encompass at least the sacrificial cap (152) and at least a portion of the decorative element (110) adjacent to the sacrificial cap (152), and wherein at least a portion of the second end (153) of the sacrificial body (150) is free of investment so as to define an opening in the mould (170); heating the decorative element (110), sacrificial body (150) and investment mould (170) until the sacrificial body (150) burns out and forms a cavity (174) within the investment mould (170), the cavity (174) comprising the shape of the sacrificial cap (152) and the at least one recess (122); filling the cavity (174) with a liquid material through the opening (172) of the mould (170); solidifying the liquid material to form a connection element (130) attached to the decorative element (110); and removing the investment mould (170).
