Interlace Knot: The Interlace knot combines linked heart shapes, straight lines, and 90 degree angles to create a unified whole. The four heart, each of which represents eternal love, point toward a center. They form a cross, which symbolizes balance. The circular shape symbolizes the relationships. As a whole, this design represents harmonious relationships with oneself and the universe. Our Interlace design jewelry is handcrafted from 100 percent recycled metals, ethically sourced stones and gems wherever possible and comes with a lifetime guarantee against defects in materials and workmanship. These heirloom quality pieces are both socially responsible and eco-friendly. Our artisanal Celtic jewelry pieces are available in gold, gold over silver and sterling silver.
