If you want an artificial crystal, there is no question of authenticity on the Internet! Because the price can only buy such things! Some workshops in small cities all over the country have production! Better, such as Hezhou, Guangxi!

But if you want to buy real crystals, I suggest not to choose them online. The first net is very illusory and deceptive! Second, I guess you don't know much about crystals either! So I'd rather go to the jewelry store in your city than spend money! Guangxi Beihai produces primitive pearls and crystals! The price is relatively cheap, and it is also very famous in the country! If you have the opportunity to travel or travel, you can consider it!
