The most efficient restoration of gem growth process
We mostly use Verneuil process, also called flame-fusion process for producing lab-created rubies and sapphires, hydrothermal growth for emerald, and some of high-quality Gems by crystal pulling method. With the development of technology, we have successfully reduced the time for lab-grow gemstones from months to weeks or even days now. And because the laboratory environment is more perfect than the natural environment, it is easier to produce high-quality gemstones, such as high-clarity emeralds and large-carat rubies.
