If one thinks of sparkling engagement rings, one immediately falls to Cartier. But the Paris label, founded by Louis Cartier in 1847, not only produces sparkling jewelery, but also luxury watches. Nevertheless, the best-known and most popular creations come from the jewelery sector - first and foremost the pieces of the Trinity collection, which was first launched in 1924 and consist of three gold tones, symbolizing different stations of a friendship: white stands for friendship, rose for love and yellow for loyalty. Of course, the experience of going to a Cartier store and picking a ring is something very special, but the real charm is mainly used vintage pieces. With some luck, you can find real treasures in second hand stores, which tell a very own story.
