This 14K yellow gold Retrouvai opal heart pendant necklace features a chain with a lobster clasp and a pendant crafted from opal with a gold-rimmed green heart in the centre. Never have we seen such a beautiful heart-shaped necklace, since old lady Rose let The Heart of the Ocean slip into the watery depths of the wreck of the Titanic. Luckily, this Retrouvai piece is the perfect replacement.
