china gold plated pendant factory How does the national standard classify jewelry and jade?

In my country’s jewelry industry, the gems are classified according to their genesis types, and gems are divided into two categories: natural and artificial. Then it is further divided according to the composition and properties of gems. When categorizing jewelry and jade, taking into account the versatility and habit in the world, try to use the generally used internationally and tend to be unified classification principles, while highlighting my country’s traditional jewelry and jade varieties featuring jade.

my country’s current national standard GB/T 16552 “Ονόματα κοσμημάτων και νεφρίτη”,. According to the cause of formation, the jewels and jade are divided into two categories, δηλαδή, natural jewels and artificial gems. Natural gems and jade include natural gems, natural jade and natural organic gems. Artificial gems include synthetic gems, man-made gems, combined gems and reconstructed gems.
