Each brand positioning and advertising investment are different, just like Pandora is a silver jewelry but the price is more expensive than gold jewelry, and people are the brands to sell. There are also brands like Chow Tai Fook. They don't sell platinum by the gram or tell you the weight by the gram. This brand is also available. If the price of this brand you mentioned is higher than other brands, you can check the purity first, and then check whether there is quality assurance. If there is no problem, you can buy it ~ there is no need to buy an international brand, it is too expensive and uneconomical.
