"A few years ago, the auction price for this necklace was 150 million. This is because this necklace isn't made from ordinary rubies. It's extremely precious and rare. Moreover, its craftsmanship can be said to be top in the world. Now, the price of this necklace is estimated to be 300 million. All the guests present will participate in the bidding and obtain what they like, but I reckon they won't be able to gather such a large sum of money in a short period of time.
