This pendant has been handmade, each element has been crafted by hand using traditional silversmithing tools and techniques and set in my home studio, Hampshire UK. This item comes with a delicate 18 inch silver chain and displayed in a black jewellery box ready for gifting. Please do let me know if you need any more info and I will be happy to help.
