At the end of each year, department stores in Japan offer what they call lucky bags sales to their customers.

The equivalent of GBP50 (US$99.1) will get you a large a sealed bag that could contain boring socks or, if you are lucky, designer wear.

This year the Takashimaya Department Store in Tokyo has come up with a super lucky bag for JPY200m (GBP1m).

Naturally, as with more downmarket lucky bags you are not to know what it contains until you hand over the cash. But it is sure to match the more than 2,000 diamonds including a massive, pear-shaped, 8-karat diamond that adorns the platinum covered purse above.

The buyer will need an awful lot of curiousity, the cost of satisfying which will surely go down in fashion history.
