The Venus Ring is made of bronze, which is a alloy of tin and copper, as in the Middle Ages these two metals were considered to bring luck and happiness. It is encrusted with an emerald on the outside, which in ancient lapidaries (books on the properties and nature of stones) is called the stone of Venus, because they attract attention and make people faithful. The hieroglyphs of the planet are engraved inside, so that only the owner knows the true purpose of the ring, while for others, it remains an ordinary piece of jewelry.
In medieval French manuscripts about Venus symbols, it is said that they help ""to establish love relationships between people":
de concilier l’amitié des personnes
French manuscript
The appearance of these symbols varies from one manuscript to another, but they always follow a common pattern and can be found in numerous sources embracing different centuries from the Middle Ages to the Modern era.
