Supply and Demand

Last week we played a game. Firstly supplying and demend was changing the value of diamonds during the game, at first the coast of diamond was normal $100 but at the middle of game the price changed to $500. But at the end the price became $50.So whlie the price was $500 we could not buy alot of diamonds because it was too expensive. How ever  as we bought expensive diamond we sold it in more expensive price. At the begining of game we just had $500 so only rings were asking to Mr Gaarvin to buy but as he got too many rings he said his not going to buy anymore rings. So we started to make different things like necklace and bracelets and crown. crown sold about $3000 and necklace were nearly $1000 and bracelets were usually $700. We also can put money in the bank.our group put $2000.At nearly end of game the price got down as I said about $50 people started to buy alot.In future when we are playing this game again I think it will be better to make things more quickly and sell it in higher price also we can sell only diamond at the end  because it got much chipper and it will be gain of selling.
