A single onyx stone necklace. It's hard to see in the photo, but it has cuts. The clear, jet-black onyx is the birthstone for August. It is said to be a protective stone that will protect you from trouble when worn. I used it at a wedding, but I'm selling it because I won't be using it anymore. If you purchase it with a dress or earrings, I will give you a discount, so please comment. Stone: Approximately 15 x 10 mm Length: Approximately 40cm (including fittings) Adjuster: Approximately 5cm
