Part of speech: noun
Definition: A carbuncle refers to a specific type of gem traditionally considered to be a red garnet, famed for its deep, crimson hue that is reminiscent of a burning ember. The term 'carbuncle' has been used in historical texts to describe jewels with a rich, red coloration, typically cut en cabochon, meaning they are polished into a smooth, rounded shape rather than being faceted. Carbuncles are often mentioned in ancient and medieval literature and lore, symbolizing wealth, protection, and power. The captivating appearance of carbuncles, combined with their historical and cultural significance, makes them a cherished choice for ornamental and jewelry purposes. Despite the historical context, in modern gemology, the term is less commonly used, with the preference being to specify the type of garnet or other gemstone.
