For example, pure natural jewelry has health care function, and some can help patients with certain diseases recover. For example, natural bian stone can improve the blood circulation of human body. But if it is synthetic, it will not have these effects.
In addition, the color summary of synthetic gems is mostly made of heavy metal element lead. The brighter the color, the higher the lead content. Wearing synthetic jewelry for a long time will separate these harmful heavy metal elements from these jewelry and attach them to your skin. The body will slowly absorb these harmful substances. Lead will not be metabolized by human body. When it reaches a certain pathogenic dose, it will seriously affect our hematopoietic function (Baidu can check). You may wear such artificial jewelry every day!
Natural jewelry has been recognized and developed by people for hundreds of years, and its spiritual value and economic value have been recognized by people, and it has been scientifically verified that trace elements and trace radiation of natural jewelry are beneficial to human body! For example, trace elements in jadeite are beneficial to human body. These are all things that synthetic gems do not have.
Because we usually have many kinds of natural gemstones, you'd better touch a specific one. I can help you explain and compare the differences between natural gemstones and synthetic gemstones.
I hope my answer can solve your problem.
