The term “carbuncle” can refer to two main meanings:
1. In a medical context, a carbuncle is a painful cluster of boils (infected hair follicles) that are connected to each other under the skin. It is often caused by bacterial infections and can result in pus-filled lumps that may require medical treatment.
2. In a gemological context, a carbuncle is a type of garnet that is typically red and has a cabochon cut. It is used in jewelry and is prized for its rich color and luster.
The word originates from the Latin “carbunculus,” meaning “little coal,” reflecting its appearance.
