Catherine would touch her neck subconsciously when thinking about Heathcliff. Just the feel of her necklace would comfort her. Jewellery can do that. The Turquoise Uncut Fancy Diamonds Wuthering Necklace is carefully crafted with turquoise and fancy cut diamonds set on sterling silver with a black rhodium plating to protect it from tarnishing. It also comes with a certificate of authenticity for added peace of mind.
