Already about 5000 years BC people used the carnelian as a seal. The gemstone could be carved rather easily, due to its softness. Since most people, even kings, could not read and write, they used their seal to acknowledge truths, deals, and orders.
Carnelian seal rings are found in Bulgaria and in Egypt and even in India.
The carnelian is not my piece of cake
In literature, you find that the carnelian is all about vibrancy, about energy and the desire or adventure. My husband will get desperate if I am going to wear jewelry with a carnelian. He already thinks I have too much energy and my too (according to him) adventurous mind brings us through the whole world, searching for gemstones.
Well, the carnelian gemstone gives protection against lack of energy, gives you an adventurous mind and leads you through boredom and anxiety.
