Answer: The "bright silver" is our original silver plated variety. It has a stainless steel core. The "925 silver" is a newer version. It is a copper based product. The copper allows for more flexibility and also makes this product a "green" option as there is less waste created in the manufacturing process. Having said this, the "bright silver" is extra durable but a little less flexible. The "925 Silver" is a little bit more temperamental but definitely more flexible.
