I haven't heard of the brand, so I'd better go to a bigger store to buy it. The process and purity are different. . . Real gold is not afraid of fire, and you will know if it is real gold after burning it. But there's no need to burn it as soon as you get it =-= it's still deformed. . If you buy K gold, you don't pay attention to purity but only bring style, just take it.
