The Celtic Knot Cross is a significant symbol in Celtic culture, blending the cross with intricate knots to represent the connection between heaven and earth. The endless knot signifies eternal life and love. Crafted from 925 sterling silver, this Viking necklace features a black zircon center for a mystical touch. The electroplated finish and oxidation-resistant technology give it a vintage look with smooth edges for comfort. Measuring 32 x 24mm (1.25 x 0.79 inches), the pendant comes with an 18-inch chain and a 2-inch extender for a perfect fit. Ideal for daily wear, it makes a meaningful gift for birthdays, anniversaries, or holidays. To maintain its shine, wear it regularly or clean it with toothpaste and water if tarnished. Store in a sealed bag when not in use to prevent oxidation. This necklace is both a stylish accessory and a cherished keepsake.
