The Calais Marine Necklace features a combination of Lapis Lazuli natural stone and a baroque pearl. The Lapis Lazuli stones are cube-cut and have been used since the Ancient Egyptian period. Lapis Lazuli derives its blue color from the minerals it contains and is believed to aid in resolving blockages in the throat and third eye chakras, promoting clear communication and understanding. It was also thought to purify the spirit from evil in Ancient Egypt and Rome.
