My friend gave me a necklace, PT950. The necklace has a pendant (I don't know whether it is diamond or zircon). The metal back of the pendant is inlaid with pt950, 0.48ct.

First of all. Let me talk about this pendant first. . Did you go to the mall to test if this is zircon? Let's talk about it first If he is a diamond. . How much is it worth? . . Generally speaking, if this 0.48 carat is true, a 48-cent diamond pendant can weigh more than 2.5 grams of platinum. . It's amazing. . Even if diamonds are similar. . The price of this pendant in the mall is at least tens of thousands (because it costs 78 thousand online). . So I think it is more likely that this is zircon. . Zircon. . Generally speaking. . This reasonable price is more than 2000 pieces (the simplest algorithm is the weight of platinum multiplied by the price of gold. Ha. Because 1 carat zircon is less than 100. )。 . Keep asking me questions.
