Almandine

Carbuncle is a red gemstone, most often red garnet.

Deep red Almadine gemstone.

So that's why in a lot of, so like in Final Fantasy VIII, it's like a little, it's a little green little beastie boy that has like a red gemstone in his forehead.

Okay.

So Metalworking technologies advanced, bringing in new casting techniques, encouraging the use of lively colors and designs, as well as precious gemstones have now made their way into the ornament.

Almadine, are you familiar? It's a garnet variety, and it seemed to be the gemstone of choice for a lot of the Middle Ages designs.

Fun and popular shapes were that of a star, a pentagon, a wheel, or a ring.

It's well documented on this podcast that I love to hate the Renaissance period.
