If the best answer is low-grade sapphires such as Shandong sapphires or Thai sapphires, each carat needs about 30 yuan, and two carats need about 60 yuan.

But if it is high-grade Kashmir sapphire or Ceylon sapphire, its price should be at least 7,000 yuan per carat. And it is almost impossible to find a two-carat sapphire, so its price is more than 20 thousand yuan.

You know, the evaluation of any gem needs to be based on grade. If you don't know the grade of a gem, you don't know its price.
