Jewelry can be divided into broad sense and narrow sense. Jewelry in the narrow sense refers to jade products. Jewelry in the broad sense should include jewelry, handicrafts or jewelry made of gold, silver and natural materials (minerals, rocks, organisms, etc.) with a certain value. Other collections are collectively referred to as jewelry, so in ancient times there was a saying of "gold and silver jewelry" to distinguish gold and silver from jewelry.

With the development of society and economy, in addition to natural gemstones and artificial gemstones, the concept of jewelry should be expanded to include gold, silver, jewelry, etc. The industry that deals in these items is collectively referred to as the "jewelry industry". The scope of "jewelry" is much larger than the concept of "gemstone" in a broad sense. In a broad sense, gemstones generally refer to those raw materials that are suitable for honing or carving into jewelry or handicrafts.

Jewelry is divided into natural gemstones (natural gemstones, natural jadeite, natural organic gemstones) and artificial gemstones (artificial gemstones, reconstructed gemstones, combined gemstones, synthetic gemstones).
