Which term is the Dutch word for a feather in a diamond?

• A. Glassie
• B. GrCnt
• C. Gletz
• D. Glide plane

Answer: (C)

Understanding that language-specific terms matter in gemology helps you read multi-language references accurately. A feather is a common fracture-inclusion inside diamonds, often appearing as wispy, feather-like lines. In Dutch gemology terminology, that feature is called gletz, so this term is the best match for describing a feather in a diamond. The remaining options don’t fit: one is a crystallographic term describing a symmetry plane (glide plane), and the others aren’t recognized Dutch terms for this specific inclusion.
