Inclusions
Inclusions are natural features found inside gemstones that can help identify their authenticity and origin. Think of them like birthmarks or fingerprints inside a gem. These internal characteristics might be tiny crystals, bubbles, or patterns that formed when the gemstone was created in nature. Gemologists use these features to tell natural gems from synthetic ones and to determine where a stone might have come from. Understanding inclusions is crucial for quality grading and pricing gemstones, as they affect a stone's clarity and value. When you see this term in a resume, it indicates someone has experience in examining and grading gemstones based on their internal features.
