Starting In 1996, Roberto Coin started embedding a little ruby in a discrete location into each of their pieces. The hallmark ruby was introduced for the very first time with the Verona Collection. The Ruby is arranged in such a way that it will have skin-to-skin contact with the person who is wearing it. It has been said for a very long time that rubies are endowed with magical qualities that provide their wearer with peace, long life, good health, and happiness. This secret ruby is a distinctive element that can be found in all of Roberto Coin's collections.
