This, 10524, has a good color and perfect cutting, but the definition is not good enough. Personally think the price is reasonable. As for whether it is expensive or not, it depends on who you compare with. It's much cheaper than big brands in shopping malls, but it's more expensive than online.

It is not recommended that you buy 0.60 SI, the cleanliness is too poor, and other cleanliness is the same, only depending on the color. D color is the highest color among diamond colors, followed by E.F.G.H But it is suggested that the landlord buy G color, which is already very white. Although the color scale of D.E.F is higher, the relative price is much higher. Diamonds with color, clarity and cut grade exceeding one carat can be preserved if the value is preserved.
