What is a trade term for any break in a diamond?

• A. Etch Channels
• B. Extra Facet (EF)
• C. Eye-visible
• D. Feather

Answer: (D)

In diamond terminology, a break or fracture inside the stone is called a feather. This term is used because it describes a wispy, hairline crack that can run through the crystal, often starting near the surface and extending inward. Feathers are internal features, and their presence helps graders communicate about structural flaws that can affect strength and appearance. Etch channels are not breaks but surface-mark patterns from chemical etching; Extra Facet refers to adding more facets during cutting, not to a flaw; Eye-visible describes whether a flaw can be seen with the naked eye, not a specific type of break. So the word feather uniquely captures the idea of a break or fracture within the diamond.
