Should Liu Yifei keep this one?

Can you take a look at everyone's sapphire? The main stone is 2.10 carats, the diamond is 1.38 carats, the gold weight is 6.78 grams, and the price is 28,000 yuan. Is it too expensive? The crystal is very clean, but I think the color is a bit light. Can you help me check if it's blackened? Should I keep it?
