Descrizione di prodotto

Loose Lab-Created Blue Sapphire Gemstone for Jewelry and Watches


Product overview


The Lab-Grown Loose Sapphire Gemstone is a high-quality synthetic sapphire produced using the Pulled Czochralski method, closely replicating the natural formation of sapphire. This method produces gemstones with vivid color, exceptional clarity, and superior brilliance, making them visually indistinguishable from natural sapphires.


Compared to other lab-grown methods, Pulled Czochralski sapphires offer better color, brightness, and chemical/physical stability, providing an affordable and high-quality alternative to natural royal blue sapphires.
