    Interesting short article.
    https://www.diamonds.net/news/NewsItem.aspx?tc_dailyemail=1&ArticleID=63345

    One reason De beers are leaders and lowest cost in the market is they have been developing this tech for decades.
    They have by far the most patents and high security.
    e.g.
    The stones showed no sign of color treatment, unlike many other chemical vapor deposition (CVD) diamonds, the GIA reported. Most producers grow CVD layers quickly, leaving a brown color, knowing they can improve them later with High Pressure-High Temperature (HPHT), Eaton-Magaña explained. For that reason, about 75% of the CVD material in this color range that the GIA has examined to date had been through HPHT treatment following growth, she noted.

    Interesting!

    Looks like they will make changes to accord with the FTC ruling, even if they don't actually start grading colour and clarity 'properly'.

    I like the fact that there is no per carat price difference since they grow a bigger stone and it costs proportionally more to grow and polish. 2 x Ct wt - 2x$'s

    2 x carat weight in natural diamonds = roughly 4 x the $$$$'s because big natural diamonds that make it to the earths surface are rare.
    Other manufacturers are trying to trade off natural diamonds and to me that is opportunistic.

    If this market takes off then De beers could rightly become the monopolist until their patents expire in 15 to 20 years by fairly and reasonably taking advantage of that R&D.
    Patents give companies monopolist rights.

    Yes, other manufacturers are trying to trade off natural diamonds and that is opportunistic and cheating!

    I wonder if the pinks and blues have been treated in some way.

    In any case, De Beers has exceeded many of the expectations. When lightbox was announced, many people thought the stones would be purposely poorly-cut or low quality just to sully the name of lab diamonds. Instead, the products are a great value. Why would I buy any other lab diamond at this point? I do wish they had released rings for v-day instead of pink hearts (talk about something no one was asking them for) and I wish they would crack on with making bracelets, but overall I'm impressed.
