Generally speaking, jewelry, handicrafts or other treasures made of natural materials other than metals with certain value, such as gold and silver, are collectively referred to as jewelry, so there is a saying of "gold and silver jewelry", and jewelry stores that operate these items are also collectively referred to as "jewelry stores".

Scientifically speaking, the concept of "jewelry" is the same as "gem" in a broad sense. Gems in a broad sense generally refer to those raw materials suitable for polishing or carving into jewelry or handicrafts.
