Modern meets vintage. Up your necklace stack with this dainty rectangle pendant emulating a deep black onyx gemstone. Wear it to give extra flair to your basic crewneck, though we especially love it paired with a deep neckline. Length: adjustable between 20" - 22". pendant: 11mm x 6mm. Our materials make for an amazing, high quality, seamless, jewelry piece with longevity. Our necklaces are plated with 18k gold, 18k rose gold, or rhodium and finished with a protective coating. A little secret we’ll keep between us: it looks way more than it costs.
