Now that it’s possible to grow affordable gems in the time it takes to watch a movie, the race is on to save the value of the most precious stone.
As well as a commitment to sustainable production, Swiss jeweler LOEV is banking on a quality designation more commonly associated with mechanical watches making the difference as it launches with a “world-first” collection of rings this month. 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 LOEV to be set into the final rings. This is installed in a vacuum chamber which is flooded with hydrocarbon gases and subjected to heat (1,652 to 2,192 degrees Fahrenheit, or 900 to 1,200 Celsius) and pressure, before a microwave beam causes carbon to condense out of a plasma cloud and crystallize to form diamonds.
