Ray Bans with golden frames

One of the most expensive models of sunglasses from Ray-Ban is Ultra Caravan Gold, a model of sunglasses whose frames are actually made ​​of gold. There are three basic versions with different lenses colours. But the Ray-Ban sunglasses have a long love story with gold and other precious metals. One of the first Aviator prototype, known as Anti-Glare, had a frame weighing 150 grams. They were made of gold-plated metal with green lenses made of mineral glass to filter out infrared and ultraviolet rays.
