How would you wear this silver bar pin set with an oval carnelian? Can you see it used at the neck of a shirt, on a jacket lapel, to hold a scarf in place, or for something else? Carnelian can range from a yellow-orange stone to reddish orange like this one. The wide variety of colors can even have a brownish tinge. Romans associated carnelian with courage and some people believe it has healing powers for the blood.
