The South China Morning Post writes that the dominant diamond player De Beers is reacting badly to the arrival of large numbers of good, tiny, lab-grown diamonds. The synthetics challenge the widely-promoted assertion that diamond prices only go up. However, labs are now able to produce chemically identical gem-quality stones, indistinguishable by the naked eye from mined diamonds, in quantities pushing 200k carats of diamonds per month. Synthetic diamonds still only account for %1 of rough diamond sales globally, but that is expected to expand to between 7.5% to 15% by 2020.

Can anyone remember when the times were not hard, and money not scarce?

I have been to several talks by ethnobotanist James Wong http://www.jameswong.co.uk/ [jameswong.co.uk]
Wasabi grows in a particular part of Japan that is damp and wet. James tells a story of being outside of a Japanese restaurant in England and picking up a wasabi plant that had self seeded outside the restaurant when they had throw out the left over bits, including the seeds.
It turns out that the UK has an excellent climate for growing Wasabi and that it would make financial sense to do so given the current costs. He often argues that growing potatoes at home is pointless as they are so cheap to buy from shops and it supports farmers if you purchase them from a shop. Growing Wasabi, yams etc makes far more sense in the UK as these are expensive with less supply.
