Morphology

gemological = gemology (transparent) = gem + ological

The meaning is directly built from gemology by adding the standard adjective-forming suffix '-ical', so the relation to gemstones is easy to infer.

Etymology

Gemological begins with gem, meaning 'precious stone', and includes the part -ology, which means 'study of' and appears in words like geology and gemologist. So gemological is about the study, testing, and grading of gems.
