Notes on Meaning

• The classification "semiprecious" is somewhat informal and commercial. In modern gemology, many stones traditionally called semiprecious (e.g., tanzanite, high-quality jade) can be very valuable, blurring the strict line between "precious" and "semiprecious." The term primarily indicates a historical and commercial distinction rather than a strict scientific one.
