Czochralski Pulled Blue Sapphire Oval Cut10x8mm (2.65ct)

The most realistic lab created stones available, grown over time from small crystals in the same conditions as natural sapphire. Unlike other lab created stones, these stones match the physical structure of a natural sapphire and not just the chemical compound. Most lab created stones are made with flame fusion. Flame fusion forms the stone in a different way than it would be formed naturally and looks different under a microscope to the real thing. This lab grown sapphire is much harder to tell apart.
