[speaker001:] Can you show me some jade, please?
[speaker002:] Yes, of course. Do you like a jade necklace?
[speaker001:] No, but I do like jade bracelets.
[speaker002:] Here are all kinds of jades. Choose whatever you like, please.
[speaker001:] Thank you. [A moment later] Oh, this one is quite impressive. I'll take it. By the way, do you sell pearl earrings?
[speaker002:] Yes. Natural pearls or cultured pearls? We have both kinds.
[speaker001:] I wonder which looks more lustrous.
[speaker002:] Well, natural pearls are of higher value, but the cultured pearls have equal lustre and are just as beautiful.
[speaker001:] Oh, I see. I think I prefer a natural one.
