But there&amp;#x27;s diamond files, diamond cutting blades&amp;#x2F;wheels&amp;#x2F;drills, you can make glass from it (really only used in labs that absolutely need them because the price), and many more uses. Many of these don&amp;#x27;t care about size, quality, or clarity. So instead of pulling from scrap material from jewelry making or rejected diamonds you could just make your own and ensure your own supply.&lt;p&gt;One of the things I&amp;#x27;ve loved about synthetic diamond prices coming down is just how cheap and available diamond cutting wheels and filing tools have become. You can now get a set of diamond files on Amazon for under $10.

Only when DeBeers realized they could push some fictious heavy marketing &amp;#x27;to prove your worth to woman you are asking to marry&amp;#x27; for those shiny stones nobody wanted to buy, people who didn&amp;#x27;t know better got manipulated into buying them. They are supposedly very common in universe, and probably in deeper Earth too.&lt;p&gt;Correction is healthy and benefits mankind long term, there was nothing good coming from ie impact on Africa. Nobody cared about that, so things are fixed from another direction.</text><parent_chain><item><author>A_D_E_P_T</author><text>Over the past 10 years, there has been an explosion in cheap lab diamond and moissanite producers in China and India.  10 years ago, it was hard to find quality lab diamonds at a reasonable price, and moissanite was still reasonably expensive at $400-600&amp;#x2F;ct.&lt;p&gt;Today, given cutthroat competition and &amp;quot;race to the bottom&amp;quot; pricing strategies, lab diamonds are ubiquitous, extremely high quality, and cheap.
