Natural Gemstone Earrings handcrafted in quartz and carnelian, natural British gemstones that I collect by hand in the lovely Northumbria region of England to bring you a ‘piece of Northumbria’. I also handcraft other untreated gemstones using lapidary techniques. Carnelian is a traditional August and September birthstone. Northumbria Gems earrings are handmade in the north-east of England and set in silver. See my other gemstone jewellery.
