Our Portuguese filigree necklaces are true masterpieces that keep the tradition — and the spirit — of Portuguese filigree alive. Filigree is an ancient metalworking technique in which fine, delicate threads of metal are bent and twisted into intricate, dazzling designs. Our filigree necklace collection ranges from minimal, elegant pieces to more elaborate, luxurious designs, all made in 19K gold, 9K gold or 925 sterling silver.
