Uh, platinum is only about 400 grams. You can buy more than 6 grams of platinum at the price you spend. Is the necklace platinum? In short, if you look at grams, it's cheap. As for the pendant with diamonds and broken diamonds, it's worthless. Small broken diamonds below 10 are hundreds at most. Hehehe, 1 and 2 cents of broken diamonds are only a few tens of dollars, so whether it is cheap or not depends on the material of platinum, the number of grams, the number of necklaces and the size of three diamonds.
