If you suffer from any metal allergies we recommend that you wear the piece in smaller periods of time to keep any reaction at a minimum. All our pieces are plated several times with the precious metals to avoid any reactions or allergies however some skin types can be very sensitive, if you know that you have very sensitive skin or the person you are purchasing the piece for has very sensitive skin we recommend you do not purchase any jewellery that is plated with precious metals and only purchase solid gold/silver jewellery.
