De Beers Fights Fakes With Technology as China's Lab-Grown Diamonds Threaten Viability of the Real Gems.

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.

    Recently, I tried out a new sushi place in town (run by Chinese). Routinely I checked the little "wasabi" sachet I got. 18%. Eighteen. BAM. With my little knowledge of Kanji I deciphered the sachet to read "Tian Peng", "Heavenly Phoenix". A little internet journey brought me to the manufacturer's site. There was no importer to Germany to be found, so that stuff must've been perfectly ... inofficial. Anyway, they had branches: one for "wasabi" and one for "bio-engineering". The wasabi branch had all sorts of packages on offer, including the pure stuff. The bio-engineering branch didn't detail as much, but what I took from it was that they must've had engineered an environment where that root happily grows far away from of Mt. Fuji. So there you go.

    Actually a Canadian, figured out how to cutivate wasabi [bbc.com]. So the restaurant's supplier or their supplier either licensed the method from him or just copied it. You need a lot of running water.
