Solid 9 Karat Yellow Gold and Matte Black Onyx 'Solo' Hook Earrings These edgy minimalist drop earrings combine a velvety matte black onyx sphere with a solid 9 karat yellow gold twisted ear hook. The 8mm round spheres of natural onyx gently dangle on their 9 karat yellow gold ear hooks with twisted detailing. Carefree pieces to wear year-round. Fun fact: Onyx is the perfect gift for people born under the zodiac sign Leo (23 June - 22 July) or a 7th anniversary. Each sphere is hand-selected for colour and quality in our Dublin studio and paired with our handmade twisted ear wires in solid 9-karat yellow gold. Gemmology: Ever since Roman times, the black color of onyx is usually enhanced. More than 2000 years ago, Roman historian Pliny described a traditional technique for darkening onyx that is still in use today: the onyx is soaked in sugar water, then placed in strong acid. After boiling for two hours, the acid eats away the sugar and water, leaving pure black carbon! Lightweight and comfortable to wear these super versatile Onyx earrings will easily go from casual daywear to elegant evening wear. They are sure to fit perfectly with any outfit in your wardrobe. Metaphysical properties: Onyx is known as a stone of strength - It is said to strengthen confidence and can help you master your destiny. It provides support in difficult times and centers your energy in times of mental or physical stress. Onyx also offers the gift of wise decisions. Wear these earrings on their own or pair them with our matching necklace and bracelet. These quietly bold earrings are wonderful as a gift for someone you love, or for yourself.
