China's Lab-Grown Diamonds Look Good

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.

    If you're a straight guy buying a wedding ring, your opinion of diamonds is not the important opinion.

    If your partner doesn't accept your beliefs, you probably shouldn't get married.

    A nice ruby, sapphire, or emerald cluster ring can be quite attractive, and all of these can be synthetic.

    DeBeers gives evil a bad name.

    Diamonds would be much more plentiful if it were not for DeBeers market control. Example: post-Soviet Russia, needed cash, and began to sell a lot of 1-2 carat stones, but DeBeers stepped-in and threatened to use their stone reserves to flood the market with that size of stone, dropping their value sharply, unless Russian producers agreed to sell only to DeBeers at DeBeers's price.

    Diamond tools. Diamond chip substrates. All of it has been stifled by DeBeers.

      We should work to fix that then. More research into CVD should help.
