Masons on Acid Series Jewellery
These pieces were designed to protect you. We protect ourselves from the elements- an umbrella, a jumper or sunscreen. We stay safe with locks, bullet proof vests and airbags, smoke alarms and ‘crash postures’. But how do you protect yourself from sinister, brain-washing-credit card taking- money laundering-usually sexually driven cult leader religions? Not a simple answer. Or is it? Although not road tested yet, these pieces flip the bird (or the evil eye in this case) to these false prophets. Repel them on street corners and ‘spiritual treks’ or in front of High Court Judges and 'men of the cloth'.
