Natural gemstone jewellery Pendants, rings and earrings handcrafted in carnelian, quartz and agate, British gemstones that I collect by hand here in the north of England – a ‘piece of Northumbria’. I shape the stones into cabochons to set in silver. I handcraft other natural gemstones including garnet and genuine Whitby jet. The faceted gemstone jewellery includes precision-cut Australian sapphire, amethyst, topaz and citrine. Traditional birthstone jewellery. Handmade in the north-east of England.
