Perhaps this isn’t surprising now that scientists can grow diamonds in just 150 minutes—faster than you can watch Oppenheimer.
has partnered with lab-grown-diamond specialists Ammil to produce what it says is the first Swiss-made jewelry collection of its kind. Relying entirely on renewable energy sources—90 percent of which come from hydroelectric power, with solar and biomass generation making up the remainder— cofounder Niels Schaefer. For any product to be certified as “Swiss Made,” 60 percent of its value must be added within Switzerland; hence the diamonds themselves are grown in Ammil’s facility in Muotathal by a process known as chemical vapor deposition before being cut and sent to India for polishing, then returning to
