These earrings feature a design with a smooth, glossy black stone set in a silver base. I forgot to ask when I bought them, but I believe the stone is onyx. I purchased them last year during a domestic trip at a shop with a nice selection of ethnic items, such as Indian cotton clothing. They are unused. - Color: Black - Material: Silver and black stone - Design: Oval - Vertical diameter: 18mm - Style: Casual - Type: Hook earrings Thank you for looking.
