The couple - who are facing separation when soccer star David heads to Italy on loan to AC Milan - believe the mystical jewellery will keep them safe.
Victoria said: "The energy they emit is incredibly powerful. These pieces act as talismans of love, healing and protection."
The Japanese necklaces - which are made of gold and silver - were gifts to each other to celebrate their 10th wedding anniversary in July next year.
They feature a pendant representing Archangel Raphael, who is widely considered to be the most powerful and loving angel in Heaven. The name Raphael means 'God has healed'.
Victoria added to Vogue magazine: "They were hand carved by a master carver in Japan, who spends most days in meditation before working."
David - who has several religious tattoos including an angel and a crucifix - also wears a mystical necklace by top jeweller Energy Muse, which is said to boost the wearer's sex life.
The couple have three children together; Brooklyn, nine, Romeo, six, and Cruz, three.
