Which term is the general trade term for a break in a gemstone, often white and feathery in appearance?

• A. Feather (Ftr)
• B. Feather
• C. Etch Channels
• D. Eye-visible

Answer: (A)

Feather describes an internal fracture in a gemstone, especially diamonds, that runs through the crystal and has a wispy, feather-like appearance. This is the general trade term used to name such breaks because they often look white or translucent and resemble a feather. It’s different from “eye-visible,” which refers to whether an inclusion can be seen with the naked eye, and from “etch channels,” which describe a separate etched feature caused by chemical processes. So, the term that best matches a break that looks white and feathery is feather.
