Light a candle (white recommended) and will the fire to be a cleansing force. Take the object you wish to bless/charge/consecrate/whatever and run it through the flame, concentrating on removing any lingering energies
Hold the piece in your palm and focus on what you want the jewellery to do (healing, help with sleep, good luck). Wear the piece until the candle burns down. Alternatively, blow the candle out, or whichever works best for you. Now any piece of jewellery can work for whatever you want, but for an extra kick, perhaps use stone jewellery.
Rose Quartz for love (family, romantic, self love)
Lapis Lazuli truth and third eye
Amethyst healing and higher though
Different metals have different uses as well, silver for the feminine and gold for the masculine.
Blessed jewellery can be a very discreet way of practising your craft as any piece can hold power and be easily used in everyday.
