Would you show me this brooch?
Yes, I would.
What is this made of?
It's sapphire. We have only one brooch of this type. Will you try it on?
Yes, I will. But how much is it?
Only 700 yuan.
It's expensive for me.
How about this one? This is 500 yuan and the same kind of material as that one.
It is genuine, isn't it?
Oh, yes. Any kind of goods are dependable as our shop is well-known throughout the city.
