Celtic knot symbols represent eternity and life's cycle while offering protection from illness or setbacks. Gifts featuring these knots convey best wishes and good luck. These high quality necklaces are crafted from certified S sterling silver, durable and safe for sensitive skin. They are non corrosive, lead and nickel free, resistant to acid and alkali, with no fading or distortion. Perfectly gift ready, each moonstone Celtic knot necklace comes in elegant packaging, eliminating the need for wrapping. This dainty jewelry suits any occasion like festivals, Valentine's Day, weddings, engagements, Christmas, graduations, dates, work, or daily life, making a thoughtful present for friends or family. As sterling silver jewelry, these pieces require simple care. Silver can oxidize when exposed to air moisture or chemicals, turning black or yellow and losing shine. Keep your necklace dry. After wearing, gently wipe it with a soft cloth to remove moisture and dirt, then store it sealed away from air contact.
