The bracelet is 6.5" in length with a solid sterling silver 1" extender chain with three rings which means this piece can be worn at 6.5", 7" and 7.5". All our items have a 1 year warranty from date of purchase Why we love 9k gold? You can keep in all day everyday even in the shower without affecting the appearance. This is the benefit of solid gold over plated. Due to the porous nature of natural opals they should never be fully immersed in water and avoid contact with chemical products such as shampoo and perfume.
