Pay homage to Celtic design with the sterling silver Celtic square necklace. The eternal knot is a classic Celtic motif and symbolises eternal loyalty, love, friendship, and faith. Crafted from polished silver, the silver pendant features eternal knot patterns that form a square shape. This necklace can be customised with chain type and charming add-ons for a personalised necklace. We love this Celtic necklace so much that we also offer it in 18ct gold plate and 18ct rose gold plate. As you’d expect from Martha Jackson, our sterling silver Celtic square necklace is made from premium recycled sterling silver. Because gifting shouldn’t cost the earth. Or blow the bank. And because we want to be kind to your skin, they are nickel free and hypoallergenic. All of our jewellery comes Gift ready. Refine the art of gifting with Martha Jackson.
