Jewelry has a broad sense and a narrow sense. Jewelry in a narrow sense only refers to jade products. Jewelry in a broad sense should include gold, silver and natural materials (minerals, rocks, organisms, etc. ). Jewelry, handicrafts or other valuable treasures are collectively called jewelry. So the old saying "gold and silver jewelry" distinguishes gold and silver from jewelry.

With the development of society and economy, the concept of jewelry should be extended to include gold, silver, jewelry and so on, in addition to natural gems and artificial products. The industries dealing in these commodities are collectively referred to as "jewelry industry". The scope of "jewelry" is much larger than that of "gem" in a broad sense. Gems in a broad sense refer to those raw materials that are suitable for polishing or carving into jewelry or handicrafts.
