For decades, we have been promised lab-grown #diamonds that are brilliant, affordable and free from the environmental pitfalls of diamond mining. But their makers have struggled to deliver quality stones at scale. The @diamondfoundry has an edge: its new hydro-powered plasma reactor in Wenatchee, Wash., constructs diamonds using a fraction of the energy of other methods, including mining. As a result, the facility can churn up to 1 million carats of diamond every year, enough for nearly 500,000 average-size #engagementrings. That speed, the company says, makes it possible for lab-grown diamonds to be cost-effectively produced at mining scale for the first time. @diamondfoundry stones (which range from a few hundred dollars to more than $30,000) are gem-quality, and the company recently partnered with @apple’s Jony Ive to create an all-diamond ring to raise money for charity.
