Autoclave Sterilisation of Jewellery

Isha Body Jewellery

Size Guide

£4.99

We strongly recommend that initial jewellery worn in a healing piercing should be left in place or where required, changed by a licenced piercer only.   Changing jewellery at home using non-sterile jewellery, before the piercing has fully healed, can risk infection.  Please consult your piercer wherever possible.  

UK standard vacuum sterilisation, autoclaved at Isha Studio.  Each item will be sterilised in a paper pouch with a light blue window.  Unless damaged, the contents remain sterile, three years from when they were autoclaved.  The process date is detailed on each pouch.

Sterilisation is only available on jewellery purchased from Isha Body Jewellery that is of suitable hypoallergenic material: Implant/Medical Grade Titanium ASTM F-136, 14ct/18ct Gold or Niobium.  Other materials will not be sterilised (non-implant grade steel or glass).

Sterilisation of jewellery is only available during the Isha Studio opening times.  

  • We list all measurements including the jewellery gauge, length or internal diameter in the product description. We recommend visiting a Body Piercer for correct sizing but apreciate this isn't always possible. Therefore, it's easiest to use your current jewellery as a guide for sizing.
