Collection: Onyx & Jet Necklaces
Onyx & Jet Necklaces
Discover our striking collection of Onyx & Jet necklaces from the Sarah Beth Collection, featuring bold and elegant designs that showcase the deep, timeless beauty of these classic dark gemstones.
Each necklace is carefully crafted in sterling silver or premium settings, highlighting the rich black tones of genuine onyx and jet. Known for their smooth polished finish and dramatic contrast against silver detailing, these gemstones create jewellery that is both sophisticated and effortlessly wearable.
Onyx has been admired since ancient times and is often associated with strength, focus and confidence, while jet—formed from fossilised wood over millions of years—is treasured for its lightweight feel and deep velvety black colour. Together, they create jewellery that is rich in heritage and character.
Our collection includes a wide variety of designs, from simple polished onyx pendants and classic solitaire styles to intricate statement necklaces featuring marcasite detailing, geometric shapes and vintage-inspired designs. Whether you prefer subtle elegance or bold statement jewellery, there is something to suit every style.
Perfect as a meaningful gift or a timeless addition to your own jewellery collection, Onyx & Jet necklaces make an ideal choice for birthdays, anniversaries or special occasions. Their enduring beauty ensures they will be worn and treasured for years to come.
