  • Curved Striations in Synthetic Color-Change Sapphire

    The curvature observed in this synthetic color-change sapphire is due to a process known as the Verneuil Process or, flame fusion. During this process, a fine crushed material is heated at extremely high temperatures. The crushed material is then melted which drips through a furnace onto a boule. This boule where the corundum cools down and crystallizes, spins and thus causes the curved striations. Natural corundum does not form this way and lacks the curved striations.
