7th - Onyx
Onyx is a hard and durable gemstone that's often used for carving and is particularly popular in men's jewellery. This anniversary is a great opportunity for men to receive jewellery as a gift, and a bold onyx ring with diamond accents is a perfect way to commemorate the occasion. For women, a combination of black onyx and white metal creates a stylish colour-blocking effect, and simple onyx stud earrings provide a stylish twist to any outfit.
