A "cross squiggly necklace" might, therefore, describe a necklace where the pendant is a cross that incorporates a squiggly or wavy pattern or design. This could mean the cross has a decorative element or engraving that features wavy lines, twists, or irregular shapes.

These necklaces can come in various styles, materials, and designs, with the cross pendant having a squiggly pattern etched, engraved, or incorporated into its design, providing a unique and visually appealing look.
