Gems are a beautiful and precious class of rock. They are brightly colored, crystal clear, shiny, hard and durable, and rare in nature. They are natural mineral crystals such as diamonds, rubies, sapphires, emeralds, etc. that can be used for jewelry, etc., and a few are natural single mineral aggregates, such as Agate, opal. There are also a few organic materials, such as amber, pearls, corals, coal and ivory, which are also included in the general gem. Jade is also the beauty of stone. It also has bright colors, hard and delicate texture, and has beautiful luster after polishing. From the current gemology, the concept of gemstones has broad and narrow meanings. The general concept of gemstones and jade is not divided. It refers to treasure jewels and jade. All materials produced by nature, which are beautiful, durable, rare and have craft value, can be processed into decorative materials, collectively called natural jewels and jade. It includes natural gemstones, natural jade, and some natural organic materials. The narrow concept also has the distinction of gems and jade: gems refer to single mineral crystals that are magnificent, crystal clear, hard, durable, rare, and can be honed into gemstone jewellery, including natural and synthetic, such as diamonds and sapphires; Jade is a collection of minerals produced by the natural world with aesthetics, durability, scarcity and process value, and a few are amorphous. Such as jade, nephrite, Dushan jade, jade jade and so on. Jade also has a narrow and broad sense. The narrow sense refers only to jadeite (represented by Burmese jade) and nephrite (represented by Hetian jade); the broad sense includes many kinds of minerals and rocks used in art and crafts. As for colored stone, it refers to low-grade arts and crafts stone which is more beautiful and delicate in color and texture, but has lower hardness and less luster but can meet the processing requirements. Some scholars advocate the inclusion of colored stones in the broad sense of jade, or temporarily use colored stones as a synonym for jade.
