Greek goldsmith Minas has created a collection of pendants for men that play on the idea of jewellery doubling up as a useful item. This pendant from the Tools collection is also a fully functioning whistle. The musical jewel has been crafted from silver in Minas’ signature curvy style. The darkened sections of metal have been heat treated to achieve the oxidised shade. Other humorous pendants in this collection include a fully functional spirit level and a magnet. The pendants are strung on a cord, available in a range of colours.
