From the French for 'a thousand grains', the tiny beads of a milgrain accent can add complexity and detail to a Lab Pink Sapphire design, as well as create a vintage or antique look. Sapphire is the birthstone of September, and pink sapphire is a very popular gemstone in jewelry today. The bright and happy color of a pink sapphire ring is both playful and trendy. Black and gold make a beautiful and elegant combination. A black onyx ring is a perfect accessory for any outfit.
